Residual current circuit breaker, 4P, AC, 25A, 30mA, instantaneous F204 AC-25/0.03 2CSF204001R1250

Protection and safety in your electrical installation

This four-pole residual current device (RCD) from ABB's F200 series is a key element ensuring safety in electrical installations. It provides protection against electric shock by detecting and interrupting circuits with leakage currents to earth. A rated current of 25A and a sensitivity of 30mA make it an ideal solution for both residential and commercial installations. The instantaneous tripping characteristic guarantees a quick response in the event of a failure.

Functionality and installation

The circuit breaker is designed for mounting on a DIN rail, which facilitates its installation and replacement. A width of 4 modules allows for efficient use of space in the switchgear cabinet. The rated voltage of 400V and the impulse voltage withstand of 4kV ensure reliable operation even in difficult conditions. Terminal block locking increases safety when connecting wires with a cross-section of 25 mm². Thanks to this, both installers and end users can be sure of the stable and safe operation of the device.

Specification and application

The circuit breaker is characterized by high resistance to surge current (0.25 kA) and short-circuit strength (1 kA), which translates into long life and reliability. Designed to protect AC circuits, it effectively reacts to sinusoidal leakage currents. The ambient temperature in operating conditions from -25°C to 55°C allows it to be used in a wide range of temperatures. The degree of protection IP2X provides basic protection against contact and ingress of solid objects. The device meets safety standards, confirming its high quality and compliance with applicable regulations.
