The Radium R3 80A Four Pole RCCB ‘AC’ Type with 300mA sensitivity is an essential safety device designed to protect electrical installations from earth leakage currents. By continuously monitoring the current flowing through the circuit, the RCCB quickly disconnects the power supply when an imbalance or leakage is detected, helping prevent electrical hazards and fire risks.

This RCCB features a four-pole design that provides full protection for three-phase systems by monitoring all three phases and the neutral line. The AC Type configuration makes it suitable for detecting sinusoidal alternating current leakage typically generated by common electrical loads such as lighting systems, heating equipment, and standard appliances.

With a rated current capacity of 80A, this RCCB is ideal for medium to high-load electrical installations in residential buildings, commercial establishments, and light industrial applications. The 300mA sensitivity level is mainly intended for fire protection and safeguarding electrical equipment by detecting potentially dangerous leakage currents.

Constructed with high-quality materials and designed for easy installation in DIN rail distribution boards, the Radium R3 RCCB ensures reliable performance, durability, and enhanced electrical safety for modern power distribution systems.
