The IMO US10C3050A is a robust UL1077 supplementary miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection for industrial control panels, OEM machinery and automation systems. Manufactured by IMO Precision Controls, this three-pole circuit breaker combines reliable electrical protection with a compact enclosure suited to demanding industrial installations.
Developed for panel builders, machine manufacturers and automation engineers, the US10C3050A offers practical supplementary circuit protection while helping to conserve valuable space inside electrical cabinets. Its DIN rail mounting arrangement enables straightforward installation, inspection and replacement within industrial control systems.
Featuring a rated current of 50 A, a C Curve tripping characteristic and a 10 kA interrupting capacity, the IMO US10C3050A is suitable for protecting three-phase machinery, industrial automation equipment and control circuits where moderate inrush currents may occur.
The IMO US10C3050A automatically disconnects a protected circuit when an overload or short-circuit fault occurs. This helps reduce the risk of damage to wiring, control components and industrial machinery while supporting safer operation and improved equipment reliability.
Its three-pole construction provides coordinated protection across three-phase circuits. The C Curve response accommodates the moderate starting currents commonly associated with motors, transformers, contactors and other inductive industrial equipment without unnecessary nuisance tripping.
Designed for standard DIN rail mounting, the US10C3050A can be integrated efficiently into control panels, machinery cabinets and electrical enclosures. Its compact format helps panel builders use available cabinet space effectively while maintaining convenient access for routine inspection and maintenance.
