Application

1. Residual current circuit breakers MBEFI are used for protection against indirect touching of parts under voltage.

2. For prevention of lasting voltage on earthed parts which should appear because of a defect in the electrical installation and for protection against direct contacts of parts under voltage in case of I n 30mA.

3. Residual current circuit breakers can be used in TN-S, TN-C, TT and IT network systems or with other words in all systems where neutral and protective conductor are separated (VDE 0100 Teil 410).

4. Types – Our programme comprises residual current circuit breakers which are sensitive to alternating residu al current (AC-type) and residual current circuit breakers which are sensitive to alternating and pulsating direct current (A-type).

Merits：

Good quality , high breaking capability, updated structure,quick trip and guide installation, competitive price,excellent and safe performance,beautiful and compact appearance, etc .
