The Radium R3 100A Four Pole RCCB ‘AC’ Type with 100mA sensitivity is a premium electrical protection device designed to safeguard three-phase installations from earth leakage currents. It continuously monitors the current flow and automatically trips the power supply when leakage is detected, helping prevent electrical accidents and reduce the risk of fire.

Its four-pole configuration ensures complete monitoring of all three phases and the neutral line, providing comprehensive protection for high-load circuits. The AC Type design accurately detects sinusoidal alternating current leakage, commonly generated by standard electrical loads including lighting systems, heating equipment, and industrial appliances.

With a 100mA sensitivity, this RCCB offers enhanced protection against leakage currents, making it suitable for environments requiring higher safety standards, such as commercial complexes, industrial facilities, and large residential installations. The 100A rated current ensures reliable performance even under heavy electrical loads.

Manufactured with high-quality materials and designed for convenient DIN rail installation, the Radium R3 RCCB delivers long-term durability, dependable tripping operation, and robust protection for modern electrical distribution systems.
