Product Overview
The RCCB-63 is a specialized safety device that continuously monitors the balance between phase (live) and neutral currents in an AC power system. If a difference (residual current) exceeds a specified threshold, the breaker quickly disconnects the circuit, minimizing risk of electric shock, fire, or equipment damage. This makes it essential in environments where personal safety and equipment protection are critical.Â
Unlike a standard MCB (which protects only against overload and short circuits), an RCCB focuses on earth leakage current detection and rapid disconnection for maximum electrical safety.Â

FAQ
An RCCB detects difference current (leakage) between phase and neutral and breaks the circuit to protect against electric shock and fire hazards.
An MCB protects against overload and short circuit, while an RCCB protects against earth leakage currents — they serve complementary safety functions. l
Â
Common residual current sensitivity options include 30 mA for personal protection, and 100 mA or 300 mA for equipment and fire safety coordination.
