Chint NB1L-B06 RCBO featuring a 6 A current rating, B curve tripping characteristic, 30 mA residual current sensitivity and 6 kA breaking capacity for reliable circuit protection.
£65.21
The Chint NB1L-B06 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 NB1L series, it combines earth leakage protection, overload protection and short-circuit protection in one modular protective device.
This RCBO is designed for single-phase circuits requiring dependable protection against both over-current faults and residual current leakage. Its B curve tripping characteristic is suitable for circuits with low inrush currents, while the 30 mA residual current sensitivity provides additional protection against electric shock.
With a rated current of 6 A, a rated voltage of 230 / 240 V AC and a short-circuit breaking capacity of 6 kA, the NB1L-B06 is well suited to lighting circuits, control circuits, auxiliary supplies and other low-load final circuits. Its DIN rail mounting format enables quick and secure installation in consumer units and distribution boards.
RCBOs such as the Chint NB1L-B06 combine the functions of an MCB and an RCD in a single device. This enables the circuit to disconnect automatically in the event of overload, short circuit or earth leakage, helping improve electrical safety and circuit reliability.
The NB1L-B06 is suitable where individual circuit protection is required. Protecting each final circuit independently helps minimise disruption, as a fault on one circuit is less likely to disconnect other protected circuits.
