The Radium R3 63A Four Pole RCCB ‘AC’ Type with 30mA sensitivity is a high-performance electrical protection device developed to safeguard three-phase installations from earth leakage currents. It continuously monitors the current flow through all phases and the neutral line, automatically disconnecting power whenever leakage is detected, effectively preventing electrical accidents and ensuring personal safety.

The four-pole design provides complete coverage for three-phase systems, while the AC Type detection mechanism accurately identifies sinusoidal alternating current leakage typically produced by lighting, heating, and standard electrical appliances. The 30mA sensitivity level offers enhanced personal protection, making this RCCB ideal for residential, commercial, and light industrial environments where safety is critical.

With a rated current of 63A, this RCCB is suitable for medium-load installations in homes, offices, and light industrial facilities. Constructed with high-quality materials and designed for easy DIN rail installation, the Radium R3 RCCB ensures reliable tripping, long-term durability, and robust protection for modern electrical distribution systems.
