The Veti EL 4-Pole RCCB is a residual current device designed to protect against electric shock and earth faults in three-phase and neutral circuits. With a 30mA sensitivity rating and 25A rated current, it automatically disconnects the circuit when a leakage current is detected, providing critical safety protection for both residential and commercial installations. Ideal for electricians and facility managers requiring reliable earth leakage protection across multi-phase systems.
