The IMO B6DR1N40-30-A is a premium Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to provide comprehensive protection against earth leakage, overloads and short circuits within a single compact device. As a Type A RCBO, it detects both alternating residual currents and pulsating DC residual currents, making it ideal for modern electrical installations containing electronic equipment, automation systems, LED lighting and variable speed drives.
Manufactured in accordance with IEC/EN 61009-1, the B6DR1N40-30-A combines the functions of an MCB and an RCD, reducing enclosure space while simplifying installation and maintenance. Its robust construction, IP20 finger-safe terminals and DIN rail mounting provide dependable protection for commercial, industrial and OEM electrical installations.
With a 40 A rated current, D curve tripping characteristic, 30 mA residual operating current, 230 V AC rated voltage and a 10 kA breaking capacity, this RCBO is ideal for transformer-fed circuits, motor control equipment, industrial machinery and other circuits subject to high inrush currents.
The IMO B6DR1N40-30-A continuously monitors overload current and residual leakage current, disconnecting the circuit immediately whenever dangerous fault conditions are detected. Its D curve characteristic allows high temporary starting currents without nuisance tripping, making it ideal for industrial motors, transformers and heavy-duty electrical equipment.
Type A residual current protection provides additional safety for circuits supplying modern electronic equipment capable of generating pulsating DC leakage currents, helping ensure compliance with current electrical installation requirements.

It provides combined overload, short-circuit and Type A residual current protection for single-phase electrical circuits requiring a 40 A D curve RCBO.
D curve RCBOs are designed for circuits supplying equipment with high starting currents, including motors, transformers and industrial machinery.
Type A RCBOs detect both alternating residual currents and pulsating DC residual currents produced by modern electronic equipment.
The B6DR1N40-30-A provides a high short-circuit breaking capacity of 10 kA for demanding electrical installations.
The device mounts directly onto a standard 35 mm DIN rail and is suitable for compatible consumer units, distribution boards and industrial control panels.
IMO B6 Type A RCBOs are trusted by electricians, panel builders and OEM manufacturers for dependable circuit protection, compact installation and reliable long-term performance across commercial and industrial electrical systems.{ "@context": "https://schema.org/", "@type": "Product", "name": "IMO B6DR1N40-30-A Type A RCBO 40A 30mA D Curve 10kA", "sku": "B6DR1N40-30-A", "mpn": "B6DR1N40-30-A", "brand": { "@type": "Brand", "name": "IMO Precision Controls" }, "category": "Residual Current Circuit Breakers", "description": "IMO B6DR1N40-30-A Type A RCBO featuring a 40 A rated current, D curve tripping characteristic, 30 mA residual current protection and 10 kA breaking capacity.", "additionalProperty": [ { "@type": "PropertyValue", "name": "Rated current", "value": "40 A" }, { "@type": "PropertyValue", "name": "Tripping characteristic", "value": "D Curve" }, { "@type": "PropertyValue", "name": "Residual current type", "value": "Type A" }, { "@type": "PropertyValue", "name": "Residual operating current", "value": "30 mA" }, { "@type": "PropertyValue", "name": "Breaking capacity", "value": "10 kA" } ] } { "@context": "https://schema.org", "@type": "FAQPage", "inLanguage": "en-GB", "mainEntity": [ { "@type": "Question", "name": "What is the IMO B6DR1N40-30-A used for?", "acceptedAnswer": { "@type": "Answer", "text": "It provides combined overload, short-circuit and Type A residual current protection for single-phase electrical circuits requiring a 40 A D curve RCBO." } }, { "@type": "Question", "name": "Why choose a D curve RCBO?", "acceptedAnswer": { "@type": "Answer", "text": "D curve RCBOs are designed for circuits supplying equipment with high starting currents, including motors, transformers and industrial machinery." } }, { "@type": "Question", "name": "What is the benefit of Type A protection?", "acceptedAnswer": { "@type": "Answer", "text": "Type A RCBOs detect both alternating residual currents and pulsating DC residual currents produced by modern electronic equipment." } }, { "@type": "Question", "name": "What is the breaking capacity of this RCBO?", "acceptedAnswer": { "@type": "Answer", "text": "The B6DR1N40-30-A provides a high short-circuit breaking capacity of 10 kA for demanding electrical installations." } }, { "@type": "Question", "name": "How is this RCBO installed?", "acceptedAnswer": { "@type": "Answer", "text": "The device mounts directly onto a standard 35 mm DIN rail and is suitable for compatible consumer units, distribution boards and industrial control panels." } } ] }
