The Schneider Electric Acti9 iID K A9R60225 residual current circuit breaker is a bipolar RCCB device rated at 25 A with 30 mA sensitivity, designed to detect earth leakage currents and automatically disconnect the circuit. Its 2-pole, AC class and instantaneous tripping configuration is especially suited to residential electrical installations supplied at 220-240 V AC.
This Schneider Electric RCD increases installation safety against insulation faults and sinusoidal alternating residual currents. It includes a test button to periodically verify operation, modular DIN rail mounting, and a compact 36 mm width, equivalent to two 18 mm modules.
The Schneider Electric A9R60225 has a rated residual current IΔn of 30 mA. This sensitivity is intended to provide additional protection for people against risks associated with earth leakage currents under the conditions specified by the regulations and by Schneider Electric.
When the difference between the current entering and returning through the circuit reaches the trip threshold, the residual current mechanism opens the poles and disconnects the supply.
The A9R60225 reference belongs to AC class. This means it is designed to detect sinusoidal alternating residual differential currents.
The selection of the RCD type must always be made according to the connected loads and the requirements of the installation. For equipment that may generate pulsating or direct residual components, other classes of RCDs, such as type A or special types, may be required depending on the application.
The Acti9 iID K features 2 poles and a rated current of 25 A. The neutral position is on the left side, according to the configuration specified by Schneider Electric.
It is especially suitable for single-phase residential circuits and other installations compatible with an operating voltage of 220 to 240 V AC at 50/60 Hz.
The residual current protection is of the instantaneous type, so it does not include an intentional time delay. When a residual current is detected that reaches the trip conditions, the device acts quickly to disconnect the circuit.
This feature distinguishes it from selective or time-delayed RCDs used in certain installations where coordination between different protection levels is required.
Schneider Electric specifies for the A9R60225 a voltage-independent residual current tripping technology.
The operation of the residual current detection mechanism does not depend on auxiliary electronic power to disconnect in the event of a leakage within its rated conditions.
The residual current circuit breaker includes a test button that allows manual checking of the protection mechanism.
Periodic testing, in accordance with Schneider Electric recommendations and the maintenance conditions of the installation, helps verify that the device can trip correctly.
The Schneider Electric A9R60225 is designed for clip-on installation on DIN rail, making it easy to integrate into residential and distribution electrical panels.
It has a width of 36 mm, equivalent to two standard 18 mm modules or four 9 mm steps. Its double-clip system also makes it easier to remove the device when a distribution comb is installed.
The RCD is designed for 50/60 Hz AC networks and has the following main electrical characteristics:
The A9R60225 is an RCCB residual current circuit breaker, so its main function is to protect against leakage currents and it does not itself include thermal-magnetic protection against overloads and short circuits.
Schneider Electric indicates the following conditional short-circuit current values when used with the specified upstream protections:
Therefore, it must be installed together with properly sized overcurrent protection for the circuit.
The tunnel-type terminals allow conductors to be connected from the top or bottom of the device.
These connection options make it easy to use in electrical panels with different cable cross-sections.
The Schneider Electric A9R60225 residual current device has reduced dimensions that help optimize the available space inside the electrical panel.
The device has an IP20 protection rating according to IEC 60529. When correctly installed inside a suitable modular enclosure, it can achieve an IP40 protection rating for the assembly.
Schneider Electric specifies the following environmental conditions:
The Acti9 iID K is designed to provide a long service life in properly sized electrical installations.
The device also offers the possibility of adding a padlock locking accessory to prevent unauthorized operation when required by the installation.
The Schneider Electric A9R60225 is designed in accordance with the main standards applicable to residual current circuit breakers without integrated overcurrent protection:
The Schneider Electric Acti9 iID K A9R60225 offers a compact solution for adding 30 mA residual current protection in single-phase circuits up to 25 A. Its bipolar configuration, AC class, instantaneous tripping and DIN rail mounting make it easy to integrate into residential electrical panels.
The test button, terminals accessible from the top or bottom, and its size of just two modules make both installation and periodic checks of the device easier.
Important: this product is an RCCB residual current circuit breaker and does not by itself provide protection against overloads or short circuits. It must be combined with a miniature circuit breaker or overcurrent protection device suitable for the circuit characteristics.
