IMO B10D1020A 20A single pole miniature circuit breaker with D curve tripping characteristic and 10kA breaking capacity for industrial, commercial and control panel circuit protection.
£7.09
The IMO B10D1020A is a robust single pole miniature circuit breaker (MCB) designed to provide reliable protection against overloads and short circuits in industrial, commercial and control panel applications. As part of the IMO B10 MCB series, it offers high breaking capacity protection in a compact DIN rail mounted format.
This MCB features a D curve tripping characteristic, making it suitable for circuits with high inrush currents such as motors, transformers, solenoids and inductive loads. Its durable construction and dependable tripping performance make it a practical choice for panel builders, electrical contractors and maintenance engineers.
With a 20A rated current, 10kA short circuit breaking capacity and operation on 230/400V AC systems, the B10D1020A provides dependable circuit protection for demanding low-voltage electrical installations where reliable fault disconnection is essential.
The IMO B10D1020A automatically disconnects the circuit when overload or short circuit conditions occur, helping to protect wiring, equipment and connected devices from electrical damage. Its D curve characteristic is designed to tolerate short-duration current surges without nuisance tripping.
This makes the B10D1020A particularly suitable for machinery, motor control circuits, transformer feeds and other equipment with inductive loads. The compact modular housing allows quick installation within distribution boards and control panels while supporting efficient maintenance and replacement.
