Type A Residual Current Circuit Breaker 25A 30mA

The 25A 30mA Type A Residual Current Circuit Breaker (RCCB / RCD) is engineered to deliver reliable earth leakage protection across modern electrical installations. Designed to detect both standard alternating residual currents and pulsating direct currents, this protective device ensures rapid disconnection in the event of an earth fault, guarding users against fatal electric shocks and reducing the risk of electrical fires.

Featuring a compact DIN rail mountable design, this circuit breaker integrates seamlessly into domestic consumer units, commercial distribution boards, and workshop power panels. Built to meet stringent electrical safety standards, it offers high-precision tripping characteristics, ensuring dependable safeguarding for appliances, electronic devices, and power distribution circuits.
