RCBOs

Residual Current Breaker with Over-Current (RCBO) devices, help protect electrical components and systems from two types of faults combining the functionality of an MCB and an RCD (residual current device). Residual current, or earth leaks occur when there is an accidental break in a circuit caused by poor electrical wiring or cutting through a power cable. Over-current comes in two forms, overload caused by too many circuit devices and a short circuit. Where an MCB protects against short circuits and overloads and an RCD protects against earth-leakage the RCBO combines both functions.

Kempston Controls, a leading stockist of electrical and electronic components, has a select range of RCBOs of all types from market leading brands such as Siemens, ABB, General Electric and more to suit whatever your electrical installation requires.
