The IMO US10D1020A is a compact 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 circuit breaker combines reliable thermo-magnetic protection with a space-saving DIN rail mounted design, making it ideal for demanding industrial environments.
Designed for machine builders, panel manufacturers and automation engineers, the US10D1020A integrates seamlessly into industrial electrical enclosures alongside PLCs, relays, contactors and power supplies. Its compact modular construction helps maximise valuable enclosure space whilst delivering dependable supplementary circuit protection.
Featuring a 20 A rated current, a D Curve tripping characteristic and a 10 kA short-circuit breaking capacity, the IMO US10D1020A is particularly suitable for transformers, solenoids, contactor coils and other inductive loads that generate high inrush currents during start-up.
The IMO US10D1020A automatically disconnects the protected circuit during overload or short-circuit conditions, helping protect wiring, electrical equipment and connected machinery from damage. Its dependable thermo-magnetic operating mechanism contributes to increased equipment reliability and reduced production downtime.
Its D Curve characteristic is engineered for circuits with higher instantaneous start-up currents, making it particularly suitable for transformer-fed circuits, industrial power supplies, contactor coils, solenoids and similar inductive applications where nuisance tripping must be minimised.
