The IMO B6CR1N40-100-A is a high-performance Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to protect electrical installations against earth leakage, overload and short-circuit faults. Combining the functions of an MCB and RCD into a single compact device, it simplifies installation whilst delivering reliable protection for residential, commercial and industrial electrical systems. Manufactured in accordance with IEC 61009, it offers dependable performance in demanding environments.
Part of the trusted IMO B6 RCBO range, this model incorporates Type A residual current protection, enabling detection of both AC and pulsating DC residual currents commonly produced by modern electronic equipment. Its compact 1 Pole + Neutral design, finger-safe terminals and DIN rail mounting make it ideal for distribution boards, control panels and OEM equipment.
Featuring a 40 A rated current, 100 mA residual operating current, a Type C tripping characteristic and a 10 kA short-circuit breaking capacity, the B6CR1N40-100-A provides reliable circuit protection for higher-load installations including machinery, commercial power distribution and industrial equipment.
The IMO B6CR1N40-100-A continuously monitors electrical circuits for overloads, short circuits and earth leakage faults. If an abnormal condition occurs, the RCBO disconnects the supply rapidly, helping protect personnel, equipment and electrical installations whilst reducing the risk of electrical fires and unplanned downtime.
Its Type A residual current detection makes it particularly suitable for modern electrical installations incorporating electronic devices, variable speed equipment, LED lighting and switched-mode power supplies that may generate pulsating DC leakage currents.

It provides combined protection against earth leakage, overload and short-circuit faults for individual electrical circuits in commercial and industrial installations.
The RCBO disconnects the circuit when earth leakage reaches approximately 100 mA, helping protect electrical installations against earth fault conditions.
The device provides Type A protection, detecting both AC and pulsating DC residual currents.
Type C RCBOs are designed for circuits supplying equipment with moderate inrush currents, including motors, transformers and industrial machinery.
The B6CR1N40-100-A is designed for installation on a standard 35 mm DIN rail within distribution boards, consumer units and industrial control panels.
IMO RCBOs are trusted by electrical contractors, panel builders and industrial engineers for delivering dependable circuit protection, compact installation and reliable long-term performance.{ "@context": "https://schema.org/", "@type": "Product", "name": "IMO B6CR1N40-100-A RCBO 40A 100mA Type A Type C 10kA", "sku": "B6CR1N40-100-A", "mpn": "B6CR1N40-100-A", "brand": { "@type": "Brand", "name": "IMO Precision Controls" }, "category": "Residual Current Circuit Breakers", "description": "IMO B6CR1N40-100-A RCBO with 40 A rated current, 100 mA Type A residual current protection, Type C tripping characteristic and 10 kA breaking capacity for commercial and industrial electrical installations.", "additionalProperty": [ { "@type": "PropertyValue", "name": "Rated current", "value": "40 A" }, { "@type": "PropertyValue", "name": "Residual current", "value": "100 mA" }, { "@type": "PropertyValue", "name": "Residual current type", "value": "Type A" }, { "@type": "PropertyValue", "name": "Breaking capacity", "value": "10 kA" }, { "@type": "PropertyValue", "name": "Pole configuration", "value": "1 Pole + Neutral" } ] } { "@context": "https://schema.org", "@type": "FAQPage", "inLanguage": "en-GB", "mainEntity": [ { "@type": "Question", "name": "What is the IMO B6CR1N40-100-A used for?", "acceptedAnswer": { "@type": "Answer", "text": "It provides combined protection against earth leakage, overload and short-circuit faults for individual electrical circuits in commercial and industrial installations." } }, { "@type": "Question", "name": "What does the 100 mA residual current rating mean?", "acceptedAnswer": { "@type": "Answer", "text": "The RCBO disconnects the circuit when earth leakage reaches approximately 100 mA, helping protect electrical installations against earth fault conditions." } }, { "@type": "Question", "name": "What type of residual current protection does it provide?", "acceptedAnswer": { "@type": "Answer", "text": "The device provides Type A protection, detecting both AC and pulsating DC residual currents." } }, { "@type": "Question", "name": "What does the Type C tripping characteristic indicate?", "acceptedAnswer": { "@type": "Answer", "text": "Type C RCBOs are suitable for circuits supplying equipment with moderate inrush currents, including motors and transformers." } }, { "@type": "Question", "name": "How is the device installed?", "acceptedAnswer": { "@type": "Answer", "text": "The device is installed onto a standard 35 mm DIN rail within distribution boards and industrial control panels." } } ] }
