Residual current circuit breaker FH202 AC-25/0.03 - 2-pole 2CSF202002R1250

Protection and safety in your electrical installation

The FH202 AC-25/0.03 residual current circuit breaker (RCCB) is a key element ensuring safety in electrical circuits. This device, with a rated current of 25A, effectively protects people from electric shock and the installation from the effects of short circuits to earth. Its construction based on AC (alternating current) technology makes it ideal for protecting circuits powering devices with characteristic leakage current, such as those with induction motors.

Functionality and installation

The FH202 two-pole circuit breaker is designed for mounting on a DIN rail, which facilitates its installation and replacement in the distribution board. It occupies 2 modules, allowing for optimal use of space in the electrical cabinet. The mechanism lock provides additional safety during operation and maintenance of the installation. The cross-section of the connectable multi-wire cable in the range of 10-25 mm² and single-wire 25 mm² provides flexibility in choosing cables tailored to specific needs.

Parameters and application

The circuit breaker is characterized by a rated differential current of 0.03A (30mA), which ensures a quick response to dangerous leakage currents. The rated voltage of 230V and the impulse voltage withstand of 4kV guarantee reliable operation under typical working conditions. The short-circuit strength of 1kA provides protection of the device in the event of a short circuit in the installation. Thanks to this, the FH202 circuit breaker finds application both in residential and commercial construction, where high reliability and safety are required. The ambient temperature in operating conditions from -5°C to 40°C allows its use in a wide range of temperatures. The degree of protection IP2X protects against touching live parts and against the ingress of solid objects larger than 12.5 mm.
