RCCB-IID Differential 4P 63A 30mA Class A-SI

The Schneider Electric Acti9 iID A9R61463 residual current circuit breaker is a 4-pole, 63 A, 30 mA sensitivity RCCB designed to detect earth leakage currents and automatically disconnect the circuit. It features superimmunized type A-SI residual current protection, instantaneous tripping, and is designed for use in three-phase networks of 380 to 415 V AC at 50/60 Hz.

A-SI technology combines the ability of a type A RCD to detect sinusoidal alternating residual currents and pulsating direct residual currents with greater immunity to electrical disturbances. This helps reduce nuisance tripping in installations with electronic equipment, LED lighting, switched-mode power supplies, variable speed drives, and other loads capable of generating harmonics or transients.

High-sensitivity 30 mA residual current protection

The Schneider Electric A9R61463 has a rated residual current sensitivity IΔn of 30 mA. This level is intended to provide additional protection for people against the risks associated with earth leakage currents, within the conditions established by the regulations and by the manufacturer.

When the device detects a current difference between the live conductors that reaches the tripping conditions, it opens the circuit to interrupt the supply.

Superimmunized type A-SI

The A-SI class is one of the most notable features of this Acti9 iID residual current device. Schneider Electric uses SI to refer to its superimmunized technology, developed to provide greater immunity against certain disturbances that can cause unwanted tripping in conventional RCDs.

As a type A residual current device, it can detect:

• Sinusoidal alternating residual currents.
• Pulsating direct residual currents.

SI technology adds greater immunity against high-frequency disturbances, harmonics, and certain transients commonly present in installations with a high level of electronics.

Fewer nuisance trips in installations with electronics

Schneider Electric recommends A-SI technology in installations where electrical disturbances can cause unwanted operation of the residual current protection.

Applications where it may be especially suitable include:

• Installations with LED lighting.
• Electronic equipment and switched-mode power supplies.
• Offices with a large number of IT devices.
• Installations with variable speed drives compatible with type A protection.
• HVAC and automation systems.
• Technical rooms and small industrial installations.
• Installations where nuisance tripping occurs due to network disturbances.

The appropriate residual current class should always be selected according to the actual characteristics of the connected loads and the regulatory requirements of each installation.

4-pole four-pole configuration

The A9R61463 reference has 4 poles and is especially suitable for three-phase circuits with neutral. Schneider Electric places the neutral pole on the left side of the device.

The simultaneous opening of the poles allows the live conductors of the circuit to be disconnected when a residual fault is detected within the device’s operating conditions.

Rated current of 63 A

The residual current circuit breaker has a rated current In of 63 A. This current corresponds to the device’s continuous carrying capacity under its rated conditions and must not be confused with the 30 mA residual current sensitivity.

Dimensioning must take into account the overcurrent protection installed upstream and the maximum expected current in the circuit.

Instantaneous residual current operation

The residual current protection of the A9R61463 is instantaneous, with no intentional time delay.

This distinguishes it from selective or time-delayed devices normally used at higher levels of an installation to achieve coordination between different residual current protections.

Voltage-independent tripping technology

Schneider Electric specifies for this model a voltage-independent residual current tripping technology. In this way, the basic residual current detection and tripping function does not require an independent auxiliary electronic supply.

The residual current device obtains the necessary operating conditions from the monitored circuit itself, within the limits defined by the manufacturer.

Resistance to impulse currents of 3 kA

The A-SI version has a resistance to impulse currents of 3,000 A. This feature is part of the immunity performance of this range and helps reduce unwanted operation caused by certain transient phenomena.

Schneider Electric identifies this 3 kA impulse withstand capability as one of the improvements of the current A-SI references compared with previous generations of residual current devices.

Conditional short-circuit current of 10 kA

The A9R61463 has a rated conditional short-circuit current of 10 kA when installed with the appropriate overcurrent protection according to the conditions established by Schneider Electric.

It also has a rated making and breaking capacity Im/IΔm of 1,500 A.

As an RCCB, these values must not be confused with the breaking capacity of a miniature circuit breaker. Overload and short-circuit protection must be provided by a properly coordinated overcurrent protective device.

Operating voltage from 380 to 415 V AC

The circuit breaker is designed to operate in networks of:

• Rated operational voltage Ue: 380-415 V AC.
• Frequency: 50/60 Hz.
• Rated insulation voltage Ui: 500 V AC.
• Rated impulse withstand voltage Uimp: 6 kV.

These characteristics allow it to be integrated into low-voltage three-phase electrical panels within the conditions indicated by Schneider Electric.

Mechanical earth fault indicator

The Acti9 iID incorporates a red mechanical indicator on the front that makes it easy to identify an operation related to an earth fault.

This signaling simplifies diagnosis inside the panel, as it allows the device that has operated due to a residual condition to be located more quickly.

Contact position indication

The A9R61463 includes visual indication of the position of its contacts. This function makes it easy to check the status of the residual current device directly from the front of the panel.

The lever-operated handle provides clear and accessible operation both during normal use and during testing and maintenance operations.

DIN rail mounting

The residual current device is designed for clip-on mounting on DIN rail, making it easy to integrate with MCBs, surge protection devices, and other Acti9 range components.

It occupies 8 modules of 9 mm, equivalent to a width of 72 mm or 4 standard 18 mm modules.

Compact dimensions

• Height: 91 mm.
• Width: 72 mm.
• Depth: 73.5 mm.
• Modular width: 4 x 18 mm modules.

These dimensions make it easy to integrate into residential, commercial, and industrial modular panels.

Conductor connection

The device terminals accept different conductor cross-sections to facilitate installation in circuits up to 63 A:

• Rigid conductor: 1 to 35 mm².
• Flexible conductor: 1 to 25 mm².

Connections must be made in accordance with the manufacturer’s instructions, the permitted conductor sizes, and the specified tightening torque to ensure a reliable electrical connection.

IP20 protection rating

The Schneider Electric A9R61463 has an IP20 protection rating according to IEC 60529. Once installed in a suitable enclosure, a higher protection rating may be achieved for the assembly, depending on the panel characteristics.

The residual current device must always be installed inside an electrical enclosure suitable for the environment and operating conditions.

Wide temperature range

The Acti9 iID A-SI is designed to operate in an ambient temperature range of -25 to 60 °C.

For storage, Schneider Electric specifies a range of -40 to 85 °C, providing flexibility for different installation and storage environments.

High durability

The Acti9 iID range is designed to provide a long service life in properly installed electrical panels. For this reference, the following is specified:

• Mechanical durability: up to 20,000 cycles.
• Electrical durability: up to 15,000 cycles.

Compatible with Acti9 accessories

The A9R61463 can be integrated with different accessories from the Schneider Electric Acti9 range, including auxiliary devices and compatible locking solutions.

Schneider Electric expressly indicates compatibility with the Acti9 padlocking device, useful for preventing unauthorized operation during certain maintenance tasks.

It can also be combined, in compatible configurations, with ARA automatic reset systems intended for 3- and 4-pole iID residual current devices.

Residual current protection for installations with electronic loads

The Schneider Electric Acti9 iID A9R61463 combines 30 mA sensitivity with type A-SI technology to provide residual current protection in three-phase installations with electronic loads. Its greater immunity to disturbances helps improve service continuity in installations where a conventional residual current device may be more susceptible to nuisance tripping.

Its 4-pole configuration, 63 A rated current, instantaneous operation, 3 kA impulse withstand, and modular DIN rail mounting make this residual current device a particularly suitable solution for residential, commercial, and professional electrical panels.

Important: the A9R61463 is an RCCB residual current circuit breaker and does not include its own protection against overloads or short circuits. It must be installed together with a correctly sized and coordinated MCB or overcurrent protective device for the circuit.
