Residual current circuit breaker, 4P, A, 100A, 30mA, instantaneous F204 A-100/0.03 2CSF204101R1900

Safety and Reliability in Your Installation

This four-pole Residual Current Device (RCD) is a key element ensuring the protection of people and electrical installations against the effects of leakage currents and earth faults. Designed for operation in AC networks with a voltage of 400V, it offers reliable protection in a wide range of applications – from home installations, through commercial, to industrial.

Protection Tailored to Your Needs

The circuit breaker is characterized by a rated current of 100A and a sensitivity of 30mA type A, which means it effectively reacts to leakage currents resulting from insulation damage or direct contact with conductive parts. The instantaneous tripping characteristic ensures a quick response in hazardous situations. The use of type A guarantees protection against sinusoidal leakage currents, which are most commonly found in electrical installations.

Installation and Compatibility

The circuit breaker design allows for mounting on a DIN rail, occupying 4 modules. It accepts solid core wires with a cross-section of 35 mm² and stranded wires up to 35 mm², providing flexibility in the selection of power cables. The mechanical lock prevents accidental changes to the settings and increases safety. The IP2X protection degree protects against touching with a finger and solid objects larger than 12.5 mm. The short-circuit strength at the level of 1 kA ensures resistance to overloads occurring during short circuits.
