The IMO UB10C1040A is a compact UL 489 miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the IMO UB10 circuit breaker series, it provides dependable branch circuit protection for industrial machinery, automation equipment, control panels and electrical distribution systems.
Featuring a 40 A rated current, a C curve trip characteristic and a 10 kA short-circuit interrupting capacity, the UB10C1040A is suitable for circuits containing equipment with moderate starting currents. Typical connected loads can include motors, transformers, solenoids, power supplies and industrial control equipment.
The UB10C1040A combines thermal overload protection with magnetic short-circuit protection to provide effective fault isolation. Its compact single-pole construction and DIN rail mounting format support straightforward installation inside machinery panels, distribution boards and industrial electrical enclosures.
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected. The thermal trip mechanism responds to sustained overload conditions, while the magnetic mechanism provides rapid disconnection during high-current short circuits. This combined protection helps prevent damage to wiring, machinery and connected electrical equipment.
The IMO UB10 range is designed for machine builders, panel manufacturers and electrical engineers requiring compact and dependable circuit protection. The C curve operating characteristic allows the breaker to accommodate moderate start-up currents while maintaining effective overload and short-circuit protection.
