The Radium R3 100A Four Pole RCCB ‘AC’ Type with 300mA sensitivity is an advanced electrical protection device designed to safeguard electrical systems from earth leakage faults. It continuously monitors the current flow in the circuit and immediately trips the power supply when leakage is detected, helping to prevent electrical accidents and potential fire hazards.

Designed for three-phase electrical installations, the four-pole configuration ensures complete protection across all phases and the neutral line. The AC Type detection makes it suitable for circuits where leakage currents are purely sinusoidal AC, commonly found in standard electrical loads such as lighting systems, heating equipment, and conventional appliances.

With a rated current of 100A, this RCCB is capable of handling higher electrical loads while maintaining consistent safety performance. The 300mA sensitivity level is primarily intended for fire protection and equipment safety, making it an ideal choice for commercial buildings, industrial facilities, and large residential distribution boards.

Manufactured with high-quality materials and a reliable tripping mechanism, the Radium R3 RCCB delivers durable performance, easy installation in DIN rail distribution boards, and dependable protection for modern electrical infrastructures.
