Wylex MCB D40 10kA 3P (3MW)
£37.36 Incl. VAT
Wylex NH Miniature Circuit Breaker is the thermal-magnetic current limiting type, having a compact construction which has been achieved by not only minimising the number of parts but also the number of welded joints and connections. Critical material selection ensures reliability and durability. Typical of this is the choice of silver graphite for the fixed contact. It has an easy to operate handle with a trip-free toggle mechanism – so even when the handle is held in the ‘on’ position the MCB is free to trip. The back-up protection is required only if the prospective short circuit current at the point of installation exceeds the breaking capacity of the MCB. When providing back-up protection consideration must be given to discrimination between the MCB and fuse. · · · D curve trip characteristic (10-20In) · · 10kA to BS EN 60898-1 (15kA to BS EN 60947-2) @ 240V AC · · Triple pole MCB · · Has box terminal, busbar aperture and DIN clip · · Energy limiting Class 3
