The IMO UB10D3063A is a high-capacity UL489 miniature circuit breaker (MCB) engineered to provide dependable overload and short circuit protection for industrial and commercial electrical systems. Manufactured by IMO Precision Controls, this robust protective device is designed for machinery, automation equipment, OEM control panels and electrical distribution systems where reliable three-phase branch circuit protection is essential.
Featuring a 3-pole configuration, a 63 A rated current and a D curve tripping characteristic, the UB10D3063A is ideally suited to circuits supplying motors, transformers, compressors and other inductive equipment that generate high inrush currents during start-up. Its compact DIN rail mounting format enables straightforward installation within industrial control panels and distribution boards.
With a 10 kA short circuit breaking capacity, thermal-magnetic protection and compliance with UL489, the UB10D3063A delivers dependable fault interruption in demanding industrial environments. Its durable construction helps minimise downtime while protecting valuable electrical equipment.
Miniature circuit breakers automatically disconnect electrical circuits when overload or short circuit conditions occur, protecting wiring, motors and connected equipment from electrical damage. The thermal element responds to sustained overload conditions, while the magnetic element provides rapid operation during severe fault conditions.
The IMO UB10D3063A features a D curve tripping characteristic that allows higher temporary inrush currents before magnetic tripping occurs, making it ideal for industrial motors, transformers and other inductive equipment while maintaining dependable protection against genuine electrical faults.
