Description

The NBN263R is a 2-pole, 63A MCB with B-type tripping and 10kA/15kA dual breaking capacity, fitted with a distinctive red toggle handle. The red toggle identifies this as the main incomer MCB within a consumer unit, and the 2-pole format provides simultaneous phase and neutral disconnection.
Used as the main incomer protective device in Hager’s SBM-series Irish consumer units (MCB incomer version), the NBN263R replaces a standard RCD incomer where full MCB protection is preferred. The high breaking capacity suits installations close to the supply transformer.
RoHS compliant and a key component of Hager’s Irish residential distribution range, the NBN263R conforms to I.S.10101 and EN 60898-1. It is compatible with Hager’s Gamma and Vega consumer unit enclosures.
