Thèse contactors are primarily for use with Direct Current loads, however they can also be used with Alternating Currents. • Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact résistance). The SW400 has double breaking main contacts with silver alloy tips which are weld résistant, hard wearing and have excellent conductivity. This compact contactor can be busbar mounted vertically or horizontally, however if mounted vertically, the coil should be at the bottom. Optional extras for the SW400 include auxiliary switches, brackets, coil finishes and magnetic latching - this allows the contactor to remain closed while consuming no coil power.
