Why Choose the Chint NB310L-2P-C16 RCBO?
The Chint NB310L-2P-C16 is a dependable Residual Current Circuit Breaker with Overcurrent Protection (RCBO) engineered to provide comprehensive protection against earth leakage, overloads and short circuits. Combining residual current protection and overcurrent protection into one compact DIN rail mounted device, it delivers reliable protection for modern low-voltage electrical installations.
As part of the Chint NB310L RCBO series, this model features a 2-pole configuration that disconnects both line and neutral during a fault, helping improve electrical safety. Its compact design makes it suitable for residential, commercial and light industrial distribution boards where panel space is at a premium.
With a rated current of 16 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-C16 is ideal for socket circuits, lighting, small motors and mixed resistive and inductive loads.
