The IMO US10D3020A is a compact and dependable UL1077 supplementary protector miniature circuit breaker designed to provide reliable overcurrent protection for industrial control circuits, OEM machinery and automation systems. Manufactured by IMO Precision Controls, it helps protect internal equipment wiring and electrical components against overload and short-circuit conditions.
Featuring a D Curve tripping characteristic, the US10D3020A is suited to circuits containing equipment with high temporary starting currents, including motors, transformers, contactors, solenoids and other inductive loads. Its thermal-magnetic operating mechanism combines overload protection with rapid short-circuit interruption, while its compact modular construction supports space-efficient installation inside electrical control panels.
With a rated current of 20 A, a three-pole configuration and a 10 kA short-circuit breaking capacity, the IMO US10D3020A provides coordinated supplementary protection for three-phase equipment circuits. Its DIN rail mounting format enables straightforward integration into industrial automation systems, machine control cabinets and OEM electrical assemblies.
The IMO US10D3020A automatically disconnects protected circuits when excessive current is detected. This helps safeguard internal equipment wiring, control components and connected electrical devices from damage caused by sustained overloads or short circuits.
Its D Curve operating characteristic allows the breaker to tolerate brief energisation currents without unnecessary tripping, making it particularly suitable for inductive loads. The three-pole arrangement provides simultaneous protection and isolation across three conductors in industrial machinery, automation equipment and three-phase control systems.

The US10D3020A provides supplementary overload and short-circuit protection for industrial control circuits, automation equipment and OEM machinery.
This supplementary protector has a rated current of 20 A.
The US10D3020A has a three-pole configuration, allowing three conductors to be protected and disconnected together.
A D Curve breaker accommodates relatively high temporary inrush currents, making it suitable for motors, transformers, contactors, solenoids and other inductive loads.
The supplementary protector is designed for installation on a standard DIN rail inside an electrical control panel, machine cabinet or equipment enclosure.
IMO supplementary protectors are widely used by panel builders, automation engineers and machine manufacturers to provide reliable circuit protection, compact installation and dependable operation within industrial electrical equipment.{ "@context": "https://schema.org/", "@type": "Product", "name": "IMO US10D3020A UL1077 Miniature Circuit Breaker 3 Pole 20A D Curve", "sku": "US10D3020A", "mpn": "US10D3020A", "brand": { "@type": "Brand", "name": "IMO Precision Controls" }, "category": "Miniature Circuit Breakers", "description": "IMO US10D3020A three-pole UL1077 supplementary protector with a 20 A rated current, D Curve tripping characteristic and 10 kA breaking capacity for industrial control and automation circuits.", "additionalProperty": [ { "@type": "PropertyValue", "name": "Rated current", "value": "20 A" }, { "@type": "PropertyValue", "name": "Number of poles", "value": "3" }, { "@type": "PropertyValue", "name": "Trip characteristic", "value": "D Curve" }, { "@type": "PropertyValue", "name": "Breaking capacity", "value": "10 kA" }, { "@type": "PropertyValue", "name": "Mounting type", "value": "DIN rail" } ] } { "@context": "https://schema.org", "@type": "FAQPage", "inLanguage": "en-GB", "mainEntity": [ { "@type": "Question", "name": "What is the IMO US10D3020A used for?", "acceptedAnswer": { "@type": "Answer", "text": "The US10D3020A provides supplementary overload and short-circuit protection for industrial control circuits, automation equipment and OEM machinery." } }, { "@type": "Question", "name": "What is the current rating of the US10D3020A?", "acceptedAnswer": { "@type": "Answer", "text": "This supplementary protector has a rated current of 20 A." } }, { "@type": "Question", "name": "How many poles does the US10D3020A have?", "acceptedAnswer": { "@type": "Answer", "text": "The US10D3020A has a three-pole configuration, allowing three conductors to be protected and disconnected together." } }, { "@type": "Question", "name": "What does the D Curve characteristic mean?", "acceptedAnswer": { "@type": "Answer", "text": "A D Curve breaker accommodates relatively high temporary inrush currents, making it suitable for motors, transformers, contactors, solenoids and other inductive loads." } }, { "@type": "Question", "name": "How is the IMO US10D3020A installed?", "acceptedAnswer": { "@type": "Answer", "text": "The supplementary protector is designed for installation on a standard DIN rail inside an electrical control panel, machine cabinet or equipment enclosure." } } ] }
