Why Choose the IMO UB10D3001A Miniature Circuit Breaker?
The IMO UB10D3001A is a high-quality 3-pole miniature circuit breaker (MCB) designed to protect three-phase electrical circuits against overloads and short circuits. As part of the proven IMO UB10 circuit protection range, this D curve breaker is ideal for industrial control panels, OEM machinery, automation systems and commercial electrical installations requiring dependable low-current protection.
Its D curve tripping characteristic allows the breaker to accommodate temporary inrush currents produced by motors, transformers, solenoids and other inductive loads without nuisance tripping, while still providing rapid fault clearance when overload or short-circuit conditions occur.
With a rated current of 1 A, a 3-pole configuration and a 10 kA breaking capacity, the UB10D3001A delivers reliable protection for sensitive three-phase circuits. The compact DIN rail-mounted design ensures fast installation in distribution boards and industrial control enclosures.
