The IMO B6DR1N20-30-A is a compact Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to provide dependable protection against earth leakage, overloads and short circuits in modern electrical installations. As a Type A RCBO, it detects both alternating residual currents and pulsating DC residual currents, making it suitable for circuits supplying electronic equipment, LED lighting, control equipment and variable speed devices.
Combining the functions of an MCB and an RCD within a single compact device, the B6DR1N20-30-A reduces installation space while providing complete circuit protection. Manufactured in accordance with IEC/EN 61009-1, it features a robust design, finger-safe terminals and reliable DIN rail mounting for residential, commercial and industrial applications.
With a 20 A rated current, D curve tripping characteristic, 30 mA residual operating current, 230 V AC operation and a 10 kA breaking capacity, this RCBO is particularly suited to protecting transformer-fed circuits, industrial machinery, motor control equipment and other loads with high inrush currents.
The IMO B6DR1N20-30-A continuously monitors overload current and residual leakage current, disconnecting the supply rapidly whenever dangerous fault conditions occur. Its D curve characteristic allows temporary high starting currents without nuisance tripping, making it particularly suitable for industrial machinery, transformers and motor-driven equipment.
Type A residual current protection makes this RCBO suitable for installations containing modern electronic equipment capable of producing pulsating DC leakage currents, providing improved protection and compliance with current installation practices.

It provides combined overload, short-circuit and Type A residual current protection for single-phase circuits requiring a 20 A D curve RCBO.
D curve RCBOs are intended for circuits with high inrush currents, including transformers, motors and industrial control equipment.
Type A RCBOs detect both alternating residual currents and pulsating DC residual currents generated by modern electronic equipment.
The B6DR1N20-30-A offers a high short-circuit breaking capacity of 10 kA.
The device clips directly onto a standard 35 mm DIN rail and fits into 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 performance across industrial, commercial and modern electrical installations.{ "@context": "https://schema.org/", "@type": "Product", "name": "IMO B6DR1N20-30-A Type A RCBO 20A 30mA D Curve 10kA", "sku": "B6DR1N20-30-A", "mpn": "B6DR1N20-30-A", "brand": { "@type": "Brand", "name": "IMO Precision Controls" }, "category": "Residual Current Circuit Breakers", "description": "IMO B6DR1N20-30-A Type A RCBO with 20 A rated current, D curve tripping characteristic, 30 mA residual current protection and 10 kA breaking capacity.", "additionalProperty": [ { "@type": "PropertyValue", "name": "Rated current", "value": "20 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 B6DR1N20-30-A used for?", "acceptedAnswer": { "@type": "Answer", "text": "It provides combined overload, short-circuit and Type A residual current protection for single-phase circuits requiring a 20 A D curve RCBO." } }, { "@type": "Question", "name": "Why choose a D curve RCBO?", "acceptedAnswer": { "@type": "Answer", "text": "D curve RCBOs are intended for circuits with high inrush currents, including transformers, motors and industrial control equipment." } }, { "@type": "Question", "name": "What does Type A protection provide?", "acceptedAnswer": { "@type": "Answer", "text": "Type A RCBOs detect both alternating residual currents and pulsating DC residual currents generated by modern electronic equipment." } }, { "@type": "Question", "name": "What is the breaking capacity of this RCBO?", "acceptedAnswer": { "@type": "Answer", "text": "The B6DR1N20-30-A offers a high short-circuit breaking capacity of 10 kA." } }, { "@type": "Question", "name": "How is this RCBO installed?", "acceptedAnswer": { "@type": "Answer", "text": "The device clips directly onto a standard 35 mm DIN rail and fits into compatible consumer units, distribution boards and industrial control panels." } } ] }
