Residual Current Circuit Breakers (RCCB)
Residual Current Circuit Breakers (RCCB)
Axiom RCCBs continuously monitor current flow and trip instantly when they detect an imbalance between the live and neutral wires, protecting people against electric shock and guarding against electrical fires caused by earth (ground) faults.
A test button and clear fault-trip indication allow frequent safety checks, while IP-20 protection and a flame-proof body and cover ensure safe operation. RCCBs protect against both direct and indirect contact, are designed to withstand high short-circuit conditions, and offer earthing protection against corrosion. Optional terminal safety shutters prevent accidental contact with live parts during installation, and the eco-friendly design takes energy conservation into account with no nuisance tripping.

Frequently asked questions
An RCCB detects an imbalance between line and neutral (current leaking to earth) and disconnects the supply, protecting against electric shock.
Yes. Combining RCCBs (earth-leakage) with MCBs (overload/short-circuit) gives comprehensive protection for the whole installation.
Axiom RCCBs are offered at 30mA, 100mA and 300mA sensitivities for residential life-protection and industrial fire-protection duties.
