Residual Current Circuit Breaker FH202 AC-40/0.03 - 2-pole 2CSF202002R1400

Safety and protection in your installation

Residual Current Device (RCD) FH202 AC-40/0.03 is a key element ensuring the safety of people and protecting the electrical installation from the effects of short circuits and earth leakage currents. The device is designed to operate in circuits with a voltage of 230V and a rated current of 40A, offering reliable protection in both domestic and professional applications. The two-pole design makes it ideal for protecting lighting circuits, socket outlets and other electrical loads.

Functionality and installation

The FH202 AC-40/0.03 RCD is characterized by high selectivity and a fast response to dangerous leakage currents (30mA). Installation is carried out on a standard DIN rail, which facilitates integration with the existing distribution board. The use of a mechanical lock prevents accidental disconnection of the device during operation. Compact dimensions (2 module width) allow for efficient use of space in the distribution cabinet.

Technical parameters and application

This residual current device has been designed with demanding applications in mind. Withstand to short-circuit currents up to 1kA and high surge current resistance (0.25kA) guarantee reliable operation even in difficult operating conditions. The cross-section of the connected multi-wire conductor up to 25mm² provides flexibility when connecting different types of cables. The device complies with the IEC/EN 61008 standard, which confirms its compliance with European safety standards. The AC characteristic makes the RCD particularly effective in detecting sinusoidal leakage currents – typical of most electrical appliances. This ensures comprehensive protection against electric shock and fire caused by insulation damage.
