Chint NB3LE-C32 RCBO featuring a 32 A current rating, C curve tripping characteristic, 30 mA residual current sensitivity and 6 kA breaking capacity for reliable circuit protection.
£52.09
The Chint NB3LE-C32 is a compact and reliable residual current operated circuit breaker with over-current protection (RCBO) designed for residential, commercial and light industrial electrical installations. As part of the Chint NB3LE series, it combines earth leakage protection, overload protection and short-circuit protection in one modular device.
This RCBO features a 1P+N configuration, making it suitable for single-phase circuits requiring both live and neutral switching. Its C curve tripping characteristic is ideal for circuits with moderate inrush currents from inductive loads, while the 30 mA residual current sensitivity provides additional protection against electric shock.
With a rated current of 32 A, a rated voltage of 240 V AC and a short-circuit breaking capacity of 6 kA, the NB3LE-C32 is ideal for socket outlet circuits, radial circuits, small motors and general-purpose final circuits. Its DIN rail mounting design enables quick and secure installation in consumer units and distribution boards.
RCBOs such as the Chint NB3LE-C32 combine the functions of an MCB and an RCD in a single device. This allows the circuit to disconnect automatically in the event of overload, short circuit or earth leakage, helping improve electrical safety while reducing the number of protective devices required within the distribution board.
The NB3LE-C32 is suitable where individual circuit protection is required. By protecting each final circuit independently, RCBOs help minimise disruption, as a fault on one circuit is less likely to disconnect other protected circuits.
