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 .
