Residual Current Circuit Breaker FH204 AC-63/0.03 - 4-pole 2CSF204002R1630

Safety and Reliability in Your Electrical Installation

This four-pole residual current circuit breaker FH204 AC-63/0.03 is a key element ensuring the protection of people and devices in electrical circuits. Designed with the needs of professional installers and the safety of end-users in mind, it guarantees effective protection against electric shock, as well as against the effects of short circuits and overloads. Its solid construction and precise operation make it an ideal choice for a wide range of applications.

Functionality and Technical Parameters

The FH204 circuit breaker is characterized by a rated current of 63A and a residual current sensitivity of 0.03A (AC). This means that it reacts to even small leakage currents, which may indicate damage to the insulation or a direct threat to health. Mounting is done on a standard DIN rail, which facilitates integration with existing electrical infrastructure. The device width is 4 modules, which allows for efficient use of space in the distribution box. The circuit breaker has a mechanical lock, preventing accidental switching on or off.

Additionally, it is worth noting its impulse withstand voltage of 0.25 kA and the ability to withstand impulse voltage up to 4 kV – these parameters testify to its durability and reliability in difficult working conditions. Suitable for operation in ambient temperature from -5°C to 40°C. The cross-section of connected wires can range from 10 to 25 mm² for stranded wires and from 25 mm² for solid wires. The rated insulation voltage Ui is 500 V, and the rated voltage is 400 V. Short-circuit withstand strength (Icw) is 1 kA.
