Why Choose the IMO B10C1020A Miniature Circuit Breaker?

The IMO B10C1020A is a high-quality single-pole miniature circuit breaker (MCB) designed to protect electrical installations against overloads and short circuits. As part of the trusted IMO B10 circuit protection range, it is ideal for commercial, industrial and OEM applications requiring dependable low voltage circuit protection.

This MCB features a C curve tripping characteristic, making it suitable for general-purpose circuits and loads with moderate inrush currents, including lighting, socket circuits, small motors and control equipment. Its compact modular design allows easy integration into distribution boards, switchgear and control panels.

With a rated current of 20 A, single-pole configuration, 10 kA short circuit breaking capacity and 230/415 V AC rated voltage, the B10C1020A provides reliable protection for professional electrical installations.
