The IMO B6CR1N20-30-A is a high-performance Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to provide comprehensive protection against earth leakage, overload and short circuit faults in residential, commercial and industrial electrical installations. Manufactured to IEC 61009, it combines the functions of an MCB and RCD into a single compact device for simplified installation and enhanced circuit protection.
Part of the reliable IMO B6 RCBO range, this device features a Type A residual current protection, enabling it to detect both AC and pulsating DC residual currents commonly generated by modern electronic equipment. Its compact single-module design saves valuable DIN rail space while delivering dependable protection for individual circuits.
Rated at 20 A with a 30 mA residual operating current, a Type C tripping characteristic and a 6 kA short-circuit breaking capacity, the B6CR1N20-30-A is ideal for protecting circuits supplying lighting, socket outlets, commercial equipment and inductive loads where moderate inrush currents are expected.
The IMO B6CR1N20-30-A continuously monitors electrical circuits for overloads, short circuits and earth leakage faults. If a fault is detected, the RCBO disconnects the supply rapidly, helping to protect personnel from electric shock whilst reducing the risk of equipment damage and electrical fires.
Its Type A residual current sensing makes it particularly suitable for installations containing modern electronic equipment, including appliances with switched-mode power supplies, LED lighting and variable speed devices that may generate pulsating DC leakage currents.

It protects electrical circuits against earth leakage, overloads and short circuits by combining RCBO and MCB functionality in one device.
Type A RCBOs detect both alternating current (AC) and pulsating direct current (DC) earth leakage, making them suitable for modern electronic equipment.
The B6CR1N20-30-A has a rated current of 20 A.
Type C devices are intended for circuits with moderate inrush currents, such as motors, transformers and commercial electrical equipment.
The RCBO is designed for quick installation onto a standard 35 mm DIN rail inside electrical distribution boards and consumer units.
IMO RCBOs are widely used by electrical contractors, panel builders and industrial engineers to deliver reliable protection against electrical faults while meeting modern installation standards.{ "@context": "https://schema.org/", "@type": "Product", "name": "IMO B6CR1N20-30-A RCBO 20A 30mA Type A Type C 6kA", "sku": "B6CR1N20-30-A", "mpn": "B6CR1N20-30-A", "brand": { "@type": "Brand", "name": "IMO Precision Controls" }, "category": "Residual Current Circuit Breakers (RCBO)", "description": "IMO B6CR1N20-30-A RCBO with 20 A rated current, 30 mA Type A residual current protection, Type C tripping characteristic and 6 kA breaking capacity for electrical circuit protection.", "additionalProperty": [ { "@type": "PropertyValue", "name": "Rated current", "value": "20 A" }, { "@type": "PropertyValue", "name": "Residual current", "value": "30 mA" }, { "@type": "PropertyValue", "name": "Residual current type", "value": "Type A" }, { "@type": "PropertyValue", "name": "Tripping curve", "value": "Type C" }, { "@type": "PropertyValue", "name": "Breaking capacity", "value": "6 kA" } ] } { "@context": "https://schema.org", "@type": "FAQPage", "inLanguage": "en-GB", "mainEntity": [ { "@type": "Question", "name": "What is the IMO B6CR1N20-30-A used for?", "acceptedAnswer": { "@type": "Answer", "text": "It protects electrical circuits against earth leakage, overloads and short circuits by combining RCBO and MCB functionality in one device." } }, { "@type": "Question", "name": "What does Type A residual current protection mean?", "acceptedAnswer": { "@type": "Answer", "text": "Type A RCBOs detect both alternating current and pulsating direct current earth leakage, making them suitable for modern electronic equipment." } }, { "@type": "Question", "name": "What is the rated current of this RCBO?", "acceptedAnswer": { "@type": "Answer", "text": "The device has a rated current of 20 A." } }, { "@type": "Question", "name": "What does the Type C tripping curve indicate?", "acceptedAnswer": { "@type": "Answer", "text": "Type C devices are designed for circuits with moderate inrush currents such as motors, transformers and commercial equipment." } }, { "@type": "Question", "name": "How is the device installed?", "acceptedAnswer": { "@type": "Answer", "text": "The RCBO is mounted onto a standard 35 mm DIN rail inside electrical distribution boards and consumer units." } } ] }
