Product Description
10KA 63A 415V B Type RCCB with DC 6mA Protection Residual Current Circuit Breaker
- Residual current circuit breakers RCCBs are the safest devices for detecting and preventing the tripping of leakage currents, thus ensuring protection against electric shocks caused by indirect contact.
- These devices must be used in series with MCBs or fuses to protect them from the potentially damaging thermal and dynamic stress of any overcurrent.
- They can also be used as the main disconnecting switch upstream of any derived MCB.
