Why Choose the Chint NB310L-2P-C32 RCBO?
The Chint NB310L-2P-C32 is a high-performance Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to provide combined protection against earth leakage, overloads and short circuits. By integrating both residual current and overcurrent protection into a single compact device, it delivers reliable protection for people, wiring and connected electrical equipment.
As part of the Chint NB310L RCBO series, this model features a 2-pole configuration that disconnects both line and neutral during fault conditions, making it suitable for residential, commercial and light industrial distribution systems. Its compact DIN rail mounted design helps maximise available space inside modern consumer units and electrical panels.
With a rated current of 32 A, a C curve tripping characteristic, Type A residual current protection, a 30 mA residual operating current and a 6 kA breaking capacity, the NB310L-2P-C32 is ideal for socket circuits, power circuits and mixed resistive and inductive loads where moderate inrush currents are expected.
Key Advantages
- Compact RCBO combining residual current and overcurrent protection.
- 32 A rated current suitable for higher-load final circuits.
- C curve tripping characteristic for mixed resistive and inductive loads.
- 2-pole configuration disconnects both line and neutral.
