    ABB RCCB

    RCCBs (also known as residual-current circuit breakers) are used to provide protection for electrical circuits themselves, as well as the workers who may be conducting maintenance works on the circuit. RCCBs offer protection from electrocution and electric shocks and also help to prevent electrical fires. In partnership with ABB, we bring you a high-quality range of reliable, high performing RCCBs.

    RCCBs work by comparing the difference in current values between neutral and live wires. Therefore, an RCCBs incoming current must match a circuits outgoing current. In a working circuit, current entering the appliance will pass through the live wire and leave through the neutral wire. If a fault occurs, some current can flow through the earth wire, or even someone performing work on the circuit. This results in unequal current flow, known as residual current.

    An ABB RCCB will work to automatically measure and disconnect the circuit whenever a fault occurs, or the current exceeds the rated sensitivity.

    What are the main benefits of an ABB RCCB?

    An RCCB purchased from ABB's extensive range ensures worldwide safety performances, certified by international marks approval. The devices also offer high quality execution and attention to details.

    What is the difference between an RCCB and an MCB?

    MCBs protect against short circuit and overload current, whilst RCCBs only protect from electric shock and earth leakage. In an ideal electrical circuit, both should be used in unison, to offer protection from all angles.
