4 Pole Residual Current Circuit Breaker, 10A/16A/20A/25A/32A/40A/63A

Four pole residual current circuit breaker (RCCB) with overload protection can monitor the difference between live and neutral currents in a three-phase electrical system. This 10 amp ~ 63 amp RCD residual current device is used in electrical systems to protect against earth leakage faults.

Tips: Difference between RCCB and MCB breaker

An RCCB (Residual Current Circuit Breaker) and an MCB (Miniature Circuit Breaker) are both safety devices but serve different purposes.

An RCCB is designed to detect and prevent electrical leakage or ground faults, where current flows through unintended paths like a human body. When it senses a difference between the live and neutral current, indicating leakage, it trips to protect against electric shocks.

An MCB is used to protect electrical circuits from overloads and short circuits. It trips when it detects excessive current flow, preventing damage to the wiring and appliances due to overheating or faults.

In summary, an RCCB protects against electric shocks and ground faults, while an MCB protects against overloads and short circuits. They are often used together for comprehensive electrical protection.
