The Starbreaker single pole MCB with Type B characteristics is suited for use on loads with little or no switching surges such as domestic applications. The MCB has an easy to use handle with trip-free toggle mechanism - so even when the handle is held in the on position the MCB is free to trip. Starbreaker MCBs are of 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. Silver graphite fixed contacts for reliability and durability.
