The IMO US10D1050A is a high-performance UL1077 supplementary miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection for industrial control panels, OEM machinery and factory automation systems. Manufactured by IMO Precision Controls, this single-pole breaker combines reliable thermo-magnetic protection with a compact DIN rail mounted design, making it ideal for demanding industrial applications.
Designed for machine builders, panel builders and automation engineers, the US10D1050A integrates seamlessly with PLCs, relays, contactors, industrial power supplies and other control equipment. Its compact modular construction helps maximise enclosure space whilst delivering dependable supplementary circuit protection.
Featuring a 50 A rated current, a D Curve tripping characteristic and a 10 kA short-circuit breaking capacity, the IMO US10D1050A is particularly suitable for transformers, solenoids, contactor coils and other inductive loads that generate high inrush currents during energisation.
The IMO US10D1050A automatically disconnects circuits experiencing overload or short-circuit conditions, helping to protect electrical conductors, machinery and sensitive industrial equipment from damage. Its dependable thermo-magnetic operating mechanism contributes to improved reliability and reduced production downtime.
The D Curve characteristic is specifically intended for circuits with high instantaneous starting currents. This makes the breaker an excellent choice for transformer-fed circuits, industrial power supplies, solenoids, contactor coils and other inductive equipment where nuisance tripping must be minimised.
