Why Choose the IMO UB10C3050A Miniature Circuit Breaker?
The IMO UB10C3050A is a robust UL 489 miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection for industrial machinery, electrical control panels and commercial power distribution systems. As part of the dependable IMO UB10 circuit breaker series, it offers effective branch circuit protection for demanding three-phase applications.
This miniature circuit breaker features a C curve tripping characteristic, making it suitable for circuits supplying motors, transformers, contactors and other equipment that can generate moderate inrush currents during start-up. Its protective operation helps isolate electrical faults while reducing the risk of unnecessary tripping under normal operating conditions.
With a rated current of 50 A, a three-pole configuration and a 10 kA short-circuit interrupting capacity, the IMO UB10C3050A is suitable for higher-load industrial circuits. Its compact DIN rail mounted construction enables straightforward installation inside machinery cabinets, control panels and electrical distribution enclosures.

Reliable Circuit Protection for Industrial Systems
Miniature circuit breakers automatically disconnect electrical circuits when excessive current or a short circuit is detected. This helps protect cables, machinery and connected equipment from electrical damage while improving installation safety, reliability and service continuity.
The C curve response of the IMO UB10C3050A makes it suitable for circuits containing inductive equipment that can produce temporary current surges during start-up. Its three-pole construction enables coordinated disconnection across three-phase circuits used in machinery, automation equipment and power distribution applications.
Typical Applications
- Industrial control panels and electrical cabinets.
- Three-phase machinery circuits.
- Motor and transformer supply circuits.
- Factory automation and production equipment.
- Commercial and industrial distribution boards.
- OEM machinery and process-control systems.
