Full Description
The Chint NB310L/3N RCBO is a high-performance residual current circuit breaker with overcurrent protection (RCBO), designed to safeguard people, equipment, and installations against overloads, short circuits, and earth leakage faults. By combining the functions of an MCB (Miniature Circuit Breaker) and an RCD (Residual Current Device) in a single compact unit, it offers reliable and space-saving protection for modern electrical systems.
This 3-pole + neutral (3P+N) RCBO is ideal for three-phase applications in commercial, industrial, and residential settings. With its C32 tripping curve, the breaker provides dependable performance for circuits with higher inrush currents, such as motors, HVAC equipment, and general-purpose loads.
Equipped with a 30 mA residual current sensitivity (Type A), it ensures advanced protection against both AC and pulsating DC leakage currents, enhancing electrical safety in line with international standards. Rated at 6 kA breaking capacity, the NB310L/3N withstands high fault currents, ensuring reliable operation in demanding environments.
