The Radium R3 63A Four Pole RCCB ‘AC’ Type with 300mA sensitivity is an advanced electrical protection device developed to safeguard electrical installations from earth leakage currents. It continuously monitors the current flow within the circuit and automatically trips the power supply when leakage is detected, helping prevent electrical hazards and reducing the risk of fire.

The four-pole configuration allows the RCCB to provide complete protection across three phases and the neutral line, making it ideal for three-phase electrical systems. The AC Type design enables accurate detection of sinusoidal alternating current leakage typically generated by standard electrical loads such as lighting systems, heating equipment, and conventional appliances.

With a rated current of 63A, this RCCB is suitable for medium-load electrical installations in residential buildings, commercial facilities, and light industrial environments. The 300mA sensitivity level is primarily intended for fire protection and equipment safety by detecting significant leakage currents before they become hazardous.

Manufactured with high-quality components and designed for easy installation in DIN rail distribution boards, the Radium R3 RCCB offers durable performance, reliable tripping functionality, and enhanced electrical protection for modern power distribution systems.
