Reliable Circuit Protection for Industrial Installations
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.
