Residual current circuit breaker

Hager Residual Current Circuit Breakers (RCCBs) are safety devices engineered to protect individuals and equipment from electric shock and fire hazards caused by earth leakage currents. They function by continuously monitoring the current balance between live conductors and disconnecting the circuit when an imbalance indicative of leakage is detected. Hager RCCBs are designed for reliable performance in residential, commercial, and industrial electrical installations.

Types and Ratings of Hager RCCBs

Hager offers a diverse range of RCCBs to cater to various application requirements:

Current Ratings: Available from 25A to 125A, accommodating different load demands.

Sensitivity (Trip Current): Options include 30mA, 100mA, and 300mA, providing varying levels of protection based on installation needs.

Pole Configurations: Offered in 2-pole and 4-pole versions, suitable for single-phase and three-phase systems.

Residual Current Types:

• Type AC: Detects alternating sinusoidal residual currents.
• Type A: Detects both alternating and pulsating direct residual currents.
