Residual current circuit breaker type G/B 4-pole FRCdM-63/4/003-G/B 167894

Safety and reliable protection of electrical installations

The Eaton FRCdM-63/4/003-G/B residual current circuit breaker (RCCB) is a key element ensuring safety in every electrical installation. The device is designed to protect people from electric shock and to protect circuits from the effects of short circuits and overloads. Its construction, based on type G/B technology, guarantees high efficiency even in the event of leakage currents with a complex waveform – which is particularly important in modern installations powering electronic devices.

Functionality and technical parameters

This circuit breaker, with a rated current of 63A and a B tripping characteristic, is perfect for protecting circuits with a high load. The B characteristic provides a quick response to overloads, while allowing for trouble-free starting of devices with motors that generate short-term current surges. The short-circuit breaking capacity at 10 kA guarantees effective protection against damage to the installation in the event of a serious failure. DIN rail mounting (4 module width) simplifies integration with existing electrical infrastructure. Additionally, a locking mechanism prevents accidental switching on of the circuit breaker after it has been switched off due to a fault.

For installers and end users

This four-pole residual current circuit breaker is a solid solution for both professionals involved in electrical installations and for end users looking for reliable protection of their home or business. The possibility of additional equipment allows the device to be adapted to the specific needs of a given installation. Compliance with safety standards (having the CE marking) and high quality of workmanship (housing with IP20 protection) ensure long-lasting and trouble-free operation. The cross-section of the connected conductor up to 35 mm² (single-wire) and 16 mm² (multi-wire) provides flexibility in choosing conductors matched to the load. The operating temperature from -25°C to 60°C allows for use in various environmental conditions.
