Reliable cable protection

MCBs protect cables against damage due to overload and short circuits: In the event of dangerously high currents, the circuit breaker’s bimetallic thermal release will disconnect the power supply. In the event of a short circuit, the electromagnetic release will disconnect the power supply in a timely manner.

A design that is standard-compliant and quality-tested

Part 1 of IEC/EN 60898 applies to AC MCBs if the rated voltage between the phases does not exceed 440 V, the rated current does not exceed 125 A and the rated breaking capacity does not exceed 25,000 A. Circuit breakers that fall within the scope of IEC/EN 60898-1 are designed to be operated by non-experts.

The right MCB for every situation

Circuit breakers with tripping characteristics B and C are the most common types. Circuit breakers with tripping characteristic B are the standard MCB type used for lighting and socket circuits.
