The IMO B6DR1N25-30-A is a high-performance Residual Current Circuit Breaker with Overcurrent Protection (RCBO) that combines earth leakage, overload and short-circuit protection within a single compact device. Designed in accordance with IEC/EN 61009-1, this Type A RCBO detects both alternating residual currents and pulsating DC residual currents, making it ideal for modern electrical installations containing electronic equipment, LED lighting, automation systems and variable speed drives.
By combining the functions of an MCB and an RCD into one unit, the B6DR1N25-30-A saves valuable space within consumer units and distribution boards while simplifying installation and maintenance. Its compact 35 mm design, finger-safe terminals and DIN rail mounting make it suitable for residential, commercial and industrial applications requiring reliable circuit protection.
With a 25 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 transformer-fed circuits, industrial machinery, motor control equipment and other applications with high inrush currents.
The IMO B6DR1N25-30-A continuously monitors both overload current and residual leakage current, disconnecting the supply immediately whenever unsafe operating conditions are detected. Its D curve characteristic is specifically designed for circuits with substantial starting currents, reducing nuisance tripping while maintaining dependable protection.
Type A residual current protection makes this RCBO suitable for installations containing electronic equipment capable of generating pulsating DC leakage currents, helping improve electrical safety in modern commercial and industrial installations.

It provides combined overload, short-circuit and Type A residual current protection for single-phase electrical circuits requiring a 25 A D curve RCBO.
D curve RCBOs are designed for circuits with high inrush currents, making them ideal for transformers, motors and industrial control equipment.
Type A RCBOs detect both alternating residual currents and pulsating DC residual currents produced by modern electronic equipment.
The B6DR1N25-30-A has a high 10 kA short-circuit breaking capacity 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, OEM machine builders and panel 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 B6DR1N25-30-A Type A RCBO 25A 30mA D Curve 10kA", "sku": "B6DR1N25-30-A", "mpn": "B6DR1N25-30-A", "brand": { "@type": "Brand", "name": "IMO Precision Controls" }, "category": "Residual Current Circuit Breakers", "description": "IMO B6DR1N25-30-A Type A RCBO featuring a 25 A rated current, D curve tripping characteristic, 30 mA residual current protection and 10 kA breaking capacity.", "additionalProperty": [ { "@type": "PropertyValue", "name": "Rated current", "value": "25 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 B6DR1N25-30-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 25 A D curve RCBO." } }, { "@type": "Question", "name": "Why choose a D curve RCBO?", "acceptedAnswer": { "@type": "Answer", "text": "D curve RCBOs are designed for circuits with high inrush currents, making them ideal for 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 produced by modern electronic equipment." } }, { "@type": "Question", "name": "What is the breaking capacity of this RCBO?", "acceptedAnswer": { "@type": "Answer", "text": "The B6DR1N25-30-A has a high 10 kA short-circuit breaking capacity 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." } } ] }
