The IMO UB10C3003A is a compact UL489 miniature circuit breaker (MCB) designed to protect low-current industrial branch circuits against overloads and short circuits. Manufactured by IMO Precision Controls, it provides dependable circuit protection for industrial control panels, automation equipment, instrumentation and OEM machinery.
The UB10C3003A combines thermomagnetic protection with a modular DIN rail-mounted design for straightforward integration into electrical enclosures. Its three-pole construction enables three connected conductors to be switched, protected and isolated simultaneously, making it suitable for three-phase control and distribution circuits.
Featuring a 3 A rated current, 3-pole configuration, C curve tripping characteristic and 10 kA short circuit interrupting capacity, the UB10C3003A provides effective protection for low-current industrial circuits that may experience moderate temporary inrush currents.
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected, helping protect cables, control devices and connected equipment. Thermomagnetic operation provides delayed tripping during sustained overload conditions and rapid interruption when a high-current short circuit occurs.
The IMO UB10C3003A is designed for industrial installations where dependable low-current protection, convenient manual resetting and compact panel integration are required. Its C curve characteristic makes it suitable for circuits containing contactors, transformers, power supplies and other equipment with moderate starting currents.
