What is An RCCB breaker?

An RCCB or residual-current circuit breaker is a safety device used to protect electrical circuits. RCCBs protect people from electric shocks, and electrocution and help prevent electrical fires. RS offers an extensive range of high-performance RCCBs and RCDs from leading brands including ABB, Schneider Electric, and Siemens.

How many Poles can a circuit breaker have?

They can be 2, 3, or 4 poles. Varying in current ratings, trip sensitivity, and tripping characteristics. All these specifications should be carefully considered depending on your individual needs and application. Browse our range of High-Quality RCCB & RCD Circuit Breakers.

What is An RCCB?

An RCCB is essentially an RCD minus the overload protection. They are typically used in applications where the risk of electric shock is limited. For more detailed information, please see our in-depth RCDs guide. RCCBs and RCDs are usually mounted on DIN rail. They can be 2, 3, or 4 poles.
