Residual current circuit breaker, FH202 AC-63/0.03, 6kA, HOME 2CSF202002R1630

Safety and protection in your electrical installation

Residual Current Circuit Breaker FH202 AC-63/0.03 is a key element ensuring the safety of people and protecting the electrical installation from the effects of short circuits and leakage currents. This device, with a rated current of 63A and a sensitivity of 0.03A, effectively detects current differences in the circuit, minimizing the risk of electric shock. The design with a lock prevents accidental switching on of the circuit breaker after tripping, which further increases the level of safety.

Functionality and application

The FH202 AC-63/0.03 circuit breaker is designed to protect circuits with a voltage of 230V and a frequency of 50Hz. Its two-pole design makes it ideal for protecting sockets, lighting and other electrical devices in residential and commercial buildings. DIN rail mounting simplifies integration with existing electrical infrastructure. The rated impulse voltage withstand value of 4kV provides resistance to overvoltages.

Parameters and construction features

This model of circuit breaker is characterized by high resistance to surge current (0.25kA) and a wide range of connection wire cross-sections – from 10 to 25 mm² for multi-strand wires and from 25 to 25 mm² for solid wires. Compact dimensions (width 2 modules, installation depth 69mm) allow for easy mounting even in tight switchboards. The degree of protection IP2X provides basic protection against contact and ingress of solid objects. The circuit breaker meets the requirements of IEC/EN 61008 standard, which guarantees its reliability and safety of use. The AC type application means that the circuit breaker reacts to both sinusoidal alternating currents and pulsating currents – typical of most household appliances.
