ABB Type A RCCBs

Please browse ABB's range of high-quality Type A residual current circuit breakers (RCCBs). RCCBs are used to protect electrical circuits, as well as any workers who may be conducting maintenance tasks on a particular circuit. An ABB Type A RCCB specifically protects against AC and pulsating DC leakage currents.

What is the difference between a Type A and Type B RCCB?

Type A RCCBs ensure protection from tripping for pulsating DC currents and residual AC currents, whereas Type B RCCBs ensure protection from tripping for both smooth and pulsating DC currents, as well as residual AC currents.
