ICV40N Differential 1P+N C 6A 30mA Class ASI

The Schneider Electric Acti9 iCV40N A9DF3606 is a combined RCBO residual current circuit breaker with overcurrent protection, 1P+N, 6 A, C curve and 30 mA sensitivity. It integrates in a single device both magnetothermal protection against overloads and short circuits and residual current protection against earth leakage currents, offering a compact solution for independently protecting single-phase circuits.

This reference includes superimmunized type A-SI residual current protection, especially suitable for installations with electronic equipment or electrical disturbances where the aim is to reduce the risk of nuisance tripping. Its rated breaking capacity is 6 kA at 230 V AC according to EN/IEC 61009-2-1 and it features instantaneous residual current tripping.

Magnetothermal and residual current protection in a single device

The A9DF3606 combines the functions of a miniature circuit breaker and a residual current device in a single two-module unit. This saves space in the distribution board and provides individual protection for each circuit.

Its main functions are:

• Protection against overloads: by thermal tripping.
• Protection against short circuits: by magnetic tripping.
• Protection against earth leakage currents: with 30 mA sensitivity.
• Additional protection for people: via high-sensitivity 30 mA residual current protection within the conditions established by the installation.
• Circuit isolation: suitable for disconnection in accordance with EN/IEC 61009-2-1.

1P+N configuration for single-phase circuits

The Schneider Electric A9DF3606 features a 1P+N configuration, with one pole protected against overcurrent and one associated neutral pole.

This arrangement is designed for single-phase circuits and allows the phase and neutral to be disconnected together when the device operates.

The neutral is located on the left side of the device.

Rated current of 6 A

The RCBO rated current is 6 A. This rating is suitable for properly sized low-current circuits, such as certain control lines, lighting, automation or small loads.

The final selection should always be made according to the circuit design current, conductor cross-section, installation method and load characteristics.

C tripping curve for magnetothermal protection

The A9DF3606 incorporates a C tripping curve. Schneider Electric sets a magnetic threshold of approximately 5 to 10 times the rated current.

The C curve allows certain transient inrush currents without causing unnecessary instantaneous tripping and is commonly used in:

• Lighting circuits.
• Electronic equipment.
• Small motors.
• Auxiliary circuits.
• Automation systems.
• Loads with moderate starting currents.

30 mA residual current sensitivity

The device has a residual current sensitivity IΔn of 30 mA, suitable for providing additional protection against certain electrical contact risks according to the characteristics and regulations of the installation.

When it detects a residual current that reaches the operating conditions, the RCBO automatically disconnects the circuit.

Superimmunized type A-SI protection

The residual current protection is type A-SI. Type A can detect sinusoidal alternating residual currents and pulsating direct residual currents, common in installations with electronic equipment.

Schneider Electric’s SI or Super Immunised technology adds greater immunity against electrical disturbances that can cause nuisance tripping in conventional protection devices.

This feature is especially useful in installations with:

• LED lighting.
• Switched-mode power supplies.
• Computer equipment.
• Control electronics.
• Automation systems.
• Loads generating harmonics.
• Electrical environments with frequent disturbances.

Schneider Electric also highlights the greater resistance of A-SI technology in certain polluted or corrosive environments.

Greater immunity against nuisance tripping

The A-SI version offers a resistance to impulse currents of up to 3 kA, helping improve service continuity against certain electrical transients.

This feature helps reduce unnecessary disconnections caused by disturbances that do not correspond to a permanent fault in the circuit.

6 kA breaking capacity

The Schneider Electric A9DF3606 has a rated breaking capacity Icn of 6,000 A at 230 V AC in accordance with EN/IEC 61009-2-1.

The manufacturer also specifies a service breaking capacity Ics of 6 kA, equivalent to 100% of the rated breaking capacity under the conditions established by the standard.

The selected breaking capacity must always be equal to or greater than the prospective short-circuit current at the point where the device will be installed.

Current limiting class 3

The RCBO has current limiting class 3. This capability helps reduce the energy flowing through the circuit during a short circuit.

Current limiting reduces thermal and electrodynamic stress on conductors and other downstream equipment.

Voltage-independent residual current tripping

Schneider Electric specifies a voltage-independent residual current tripping technology.

This feature allows the residual current detection function to maintain its operating principle without depending on an external auxiliary electronic supply.

Instantaneous residual current operation

The earth leakage protection is instantaneous, with no intentional tripping delay.

When the residual current reaches the operating threshold, the RCBO disconnects the circuit without applying additional selective time delay.

230 V AC rated voltage

The A9DF3606 is designed for single-phase circuits with the following electrical characteristics:

• Rated operational voltage Ue: 230 V AC.
• Frequency: 50/60 Hz.
• Rated insulation voltage Ui: 400 V AC.
• Rated impulse withstand voltage Uimp: 4 kV.
• Overvoltage category: III.
• Pollution degree: 3.

VisiTrip for easier diagnosis

The Acti9 iCV40N features VisiTrip indicators that make it easy to quickly locate the circuit that has tripped and help visually identify the device status.

This signalling reduces the time needed to diagnose an issue in panels with numerous protection devices.

VisiSafe to confirm contact opening

VisiSafe technology includes a visual indication that allows the physical opening of the contacts to be checked.

This feature is especially useful during maintenance tasks and complements the device’s suitability for isolation functions.

Compact 2-module format

The Schneider Electric A9DF3606 combines magnetothermal and residual current protection in a width of only 36 mm.

This is equivalent to:

• 2 standard 18 mm modules.
• 4 steps of 9 mm.

Its design helps optimize available space in residential and commercial distribution boards compared with a solution using separate MCB and RCD devices.

DIN rail mounting

The device is installed by clip-on mounting on a DIN rail, making installation and replacement inside the electrical panel easier.

It is also compatible with suitable Schneider Electric comb busbars and distribution systems, with connection possible from the top or bottom depending on the configuration used.

Complete protection in just two modules

The Schneider Electric Acti9 iCV40N A9DF3606 combines 6 A magnetothermal protection and 30 mA residual current protection in a single device. In this way, it protects a circuit individually against overloads, short circuits and earth leakage while occupying only two modules in the panel.

Its superimmunized A-SI technology, 6 kA breaking capacity, C curve, VisiTrip and VisiSafe signalling and DIN rail mounting make it a particularly suitable solution for installations with electronics and circuits where improved service continuity is required without giving up high-sensitivity residual current protection.

Important: the RCBO must be selected by checking the design current, conductor cross-section, prospective short-circuit current, required residual current sensitivity and characteristics of the connected loads. The A-SI class must also be verified against the specific residual current protection needs of the installed equipment.
