ABB System proM RCBO DS271

ABB DS 271 RCCBThis range is now Obsolete. Please see the conversion chart at the bottom of this page to cross reference to the new DSE range.

Single pole and solid neutral RCBO DS271 series, rating 6 to 32A, BS EN 61009-2-2, Class AC


The ABB DS 271 residual current circuit breakers with integral overcurrent protection (RCBO) combines the functions of a miniature circuit breaker (MCB) and a residual current circuit breaker (RCCB) in a compact space saving 17.5 mm module.

It provides supplementary earth leakage protection for individual circuits in order to protect people from the risk of electrocution and fires caused by electrical faults while also providing overcurrent protection for equipment and cables.

The ABB DS271 RCBO is designed to meet the requirements of BS EN 61009 and features a single pole and solid neutral and is supplied with an 800mm flying neutral lead. They have an operating voltage of 230 V and are ideally suited for installation in consumer units, such as ABB’s new Housemaster range, or for use in distribution boards, and will also snap-on to DIN rails to IEC 60715.

The RCBO covers a range of six rated currents from 6A up to 32A and is available in two fixed levels of sensitivity of either 10 mA or 30 mA. It is available in tripping curves B and C in accordance with BE EN 60898 and as standard is of Type AC operation.

Devices of A Type operation are available to order.
