domeashop Differential block

Discover our selection of differential blocks designed to complement a modular circuit breaker in an electrical panel. When used with a compatible circuit breaker, the residual current device provides protection against insulation faults and ground leakage currents, with typical sensitivity levels such as 30 mA for personal protection. Its use is recommended when installing, renovating, or expanding an electrical system that requires a residual current device (rcd) suitable for the circuit. The Hager, ABB, Legrand, Schneider Electric, and Eaton product lines cater to a variety of needs: single-phase, three-phase, AC-type, type A, or four-pole.

It adds residual current protection to a compatible modular circuit breaker to detect ground fault currents.

The residual current device is used in conjunction with a circuit breaker, whereas a residual current switch provides protection only against ground faults, without protection against overcurrent.

A threshold of 30 mA is commonly used to protect people in low-voltage electrical systems.

You must check the brand, model series, number of poles, rating, type of ground fault circuit interrupter, and compatibility with the associated circuit breaker.

Yes, four-pole models are designed for three-phase installations with a neutral, provided they are compatible with the circuit breaker.
