The IMO UB10D3020A is a dependable UL489 miniature circuit breaker (MCB) designed to protect industrial and commercial electrical circuits against overloads and short circuits. Manufactured by IMO Precision Controls, this compact protective device is suitable for machinery, control panels and electrical distribution systems where reliable three-phase circuit protection is required.
Featuring a 3-pole configuration, a 20 A rated current and a D curve tripping characteristic, the UB10D3020A is particularly well suited to circuits supplying motors, transformers, solenoids and other inductive equipment. The D curve characteristic accommodates the temporary high inrush currents commonly produced when this type of equipment starts.
With a 10 kA short circuit breaking capacity, the UB10D3020A provides effective fault interruption in demanding industrial environments. Its compact modular format and standard DIN rail mounting make it easy to incorporate into new control panels or use when maintaining existing electrical installations.
Miniature circuit breakers automatically disconnect an electrical circuit when an overload or short circuit is detected. The thermal element responds to sustained overcurrent conditions, while the magnetic element provides rapid operation during severe short circuit faults. This helps protect cables, machinery and connected electrical equipment from damage.
The D curve characteristic of the IMO UB10D3020A permits higher temporary starting currents before magnetic tripping occurs. This makes the breaker suitable for industrial loads that require significant current during start-up while retaining dependable protection against genuine electrical faults.
