This compact busbar mounted contactor follows the recognised design of the SW250 s驩ries of contactors and is devised for uninterrupted loads. They are primarily for use with direct current loads but can be used for alternating current loads. Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance). The SW225 features single pole double breaking main contacts with silver alloy tips which are weld rsistant, hard wearing and have excellent conductivity. Mounting can either be horizontal or vertical. The SW225 is easy to install, with "L" Shape Mounting bracket kits fitted as a standard option, or alternatively the M4 tapped holes Application Uninterrupted Thermal Current Rating ('th) 225A A Intermittent Current Rating: A 30% Duty 410A A 40% Duty 355A A 50% Duty 320A A 60% Duty 290A A 70% Duty 270A A Rated Fault Current Breaking Capacity ('cn) Resistive Load*: SW225 330A at 60V D.C.
