The IMO UB10D3004A is a high-performance 3-pole miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in three-phase electrical systems. As part of the trusted IMO UB10 circuit protection range, this D curve breaker is ideal for industrial control panels, machinery, OEM equipment and commercial electrical installations where inductive loads generate high inrush currents.
Featuring a D curve tripping characteristic, the UB10D3004A allows temporary starting currents from motors, transformers, solenoids and compressors to pass without nuisance tripping, while providing rapid and reliable disconnection during genuine overload and short-circuit conditions.
With a rated current of 4 A, a 3-pole configuration and a 10 kA breaking capacity, the UB10D3004A delivers reliable protection for demanding industrial applications. Its compact DIN rail-mounted design enables fast installation within distribution boards and electrical control panels.
Miniature circuit breakers automatically disconnect electrical circuits whenever overload or short-circuit conditions occur, helping protect wiring, machinery and connected equipment from electrical damage. The thermo-magnetic mechanism combines dependable overload protection with rapid magnetic fault interruption to maximise system safety and reliability.
The IMO UB10 series is widely specified for industrial automation, OEM machinery and commercial electrical installations. Its D curve characteristic is particularly suited to motors, transformers, compressors and other inductive equipment that generate high temporary starting currents.

It protects three-phase electrical circuits against overloads and short circuits, particularly circuits supplying motors, transformers and other inductive equipment with high starting currents.
The UB10D3004A has a 4 A rated current.
D curve breakers tolerate higher temporary inrush currents than B or C curve breakers, making them ideal for motors, transformers, compressors and other inductive loads.
The breaker has a 10 kA short-circuit breaking capacity, providing dependable protection in demanding electrical installations.
The breaker is designed for installation on a standard 35 mm TS35 DIN rail inside distribution boards, switchboards and industrial control panels.
IMO circuit protection products are trusted worldwide by electrical engineers, OEM manufacturers and panel builders for dependable overload protection, straightforward installation and long-term reliability in demanding industrial environments.{ "@context": "https://schema.org/", "@type": "Product", "name": "IMO UB10D3004A Miniature Circuit Breaker 4 A 3 Pole D Curve", "sku": "UB10D3004A", "mpn": "UB10D3004A", "brand": { "@type": "Brand", "name": "IMO" }, "category": "Miniature Circuit Breakers", "description": "IMO UB10D3004A 4 A 3-pole D curve miniature circuit breaker with a 10 kA breaking capacity for industrial three-phase circuit protection.", "additionalProperty": [ { "@type": "PropertyValue", "name": "Rated current", "value": "4 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": "35 mm TS35 DIN rail" } ] } { "@context": "https://schema.org", "@type": "FAQPage", "inLanguage": "en-GB", "mainEntity": [ { "@type": "Question", "name": "What is the IMO UB10D3004A used for?", "acceptedAnswer": { "@type": "Answer", "text": "It protects three-phase electrical circuits against overloads and short circuits, particularly circuits supplying motors, transformers and other inductive equipment with high starting currents." } }, { "@type": "Question", "name": "What is the current rating?", "acceptedAnswer": { "@type": "Answer", "text": "The UB10D3004A has a 4 A rated current." } }, { "@type": "Question", "name": "Why choose a D curve circuit breaker?", "acceptedAnswer": { "@type": "Answer", "text": "D curve breakers tolerate higher temporary inrush currents than B or C curve breakers, making them ideal for motors, transformers, compressors and other inductive loads." } }, { "@type": "Question", "name": "What is the breaking capacity?", "acceptedAnswer": { "@type": "Answer", "text": "The breaker has a 10 kA short-circuit breaking capacity for dependable fault protection." } }, { "@type": "Question", "name": "How is the UB10D3004A installed?", "acceptedAnswer": { "@type": "Answer", "text": "The breaker is designed for mounting onto a standard 35 mm TS35 DIN rail inside distribution boards, switchboards and industrial control panels." } } ] }
