OFA Electrical
1 / 3
An OFDX 4P RCCB is a four-pole electrical safety device designed to detect residual current leakage and automatically disconnect power to prevent electrical shock, injuries, and potential fire hazards in three-phase electrical circuits.
A 4P RCCB is specifically designed for three-phase four-wire electrical systems. It provides comprehensive current leakage protection across all three phase lines plus the neutral line simultaneously.
No, a standard RCCB primarily detects leakage current to prevent electric shocks. For full protection against overloads and short circuits, it should be paired with suitable Miniature Circuit Breakers (MCBs) or overcurrent protection devices.
It is typically installed in distribution boards for commercial, industrial, and residential three-phase electrical distribution systems requiring high-reliability ground fault protection.
It is recommended to press the built-in "Test" (T) button monthly to ensure the internal tripping mechanism operates properly under fault conditions.
