IMO B10D1040A 1 pole 40A D curve miniature circuit breaker with 10 kA breaking capacity for industrial and commercial circuit protection.
£7.96
The IMO B10D1040A is a high-performance 1 pole miniature circuit breaker (MCB) designed to provide reliable protection against overloads and short circuits in industrial, commercial and OEM electrical installations. Manufactured by IMO Precision Controls, this compact protective device is built for dependable circuit protection in modern distribution boards, machinery and control panels.
Featuring a D curve tripping characteristic, the B10D1040A is particularly suitable for circuits with high inrush currents, including motors, transformers, solenoids and inductive loads. Its DIN rail mounted format ensures quick, secure and space-saving installation inside electrical enclosures.
With a 40 A rated current, 1 pole configuration, 230/415 V AC rated voltage and a 10 kA short circuit breaking capacity, the IMO B10D1040A delivers robust circuit protection for demanding electrical applications.
Miniature circuit breakers automatically disconnect electrical circuits during overload or short circuit conditions, helping protect wiring, connected equipment and personnel. The IMO B10D1040A provides reliable fault protection while supporting safe and efficient operation across industrial and commercial installations.
Its D curve characteristic allows the breaker to tolerate higher start-up currents before tripping, making it well suited to inductive equipment where nuisance tripping must be reduced without compromising protection.
