The Radium R3 25A Four Pole RCCB ‘AC’ Type with 300mA sensitivity is an essential electrical protection device designed to safeguard electrical installations from earth leakage currents. It continuously monitors the current flow within the circuit and automatically disconnects the power supply when leakage is detected, helping prevent electrical accidents and potential fire hazards.

The four-pole configuration provides full protection for three-phase systems by monitoring all three phases along with the neutral line. The AC Type detection mechanism is specifically designed to detect sinusoidal alternating current leakage, which is commonly produced by standard electrical loads such as lighting systems, heating equipment, and conventional appliances.

With a rated current of 25A, this RCCB is well suited for lower to medium load electrical installations in residential buildings and small commercial spaces. The 300mA sensitivity level is primarily intended for fire protection and equipment safety by identifying significant leakage currents before they become hazardous.

Manufactured using high-quality materials and designed for easy DIN rail installation inside distribution boards, the Radium R3 RCCB ensures reliable operation, long-lasting durability, and enhanced electrical protection for modern power distribution systems.
