Molded case is molded from high mechanical and high dielectric strength engineered plasticTrip indication is shown by handle position midway between ON and off to reset the trip mechanism, move the handle to extreme off then to ON positionQuick-make, quick-break, trip-free mechanism minimizes arcing during breaker operation, contacts cannot be ''teased'' into positionTrip-free mechanism is independent of manual handle control, the breaker trips under short circuit or overload, even though the operating handle is held in ON positionVERIFIER™ "twist-to-trip" and ''push-to-trip'' mechanically simulates over current tripping through actuation of linkages not operated by the on-off handleCommon trip bar assures instant disconnect of all conductors when an overload or short circuit occurs on any one conductor in the circuit or an accessory trip device operatesSilver alloy contacts combine the conductive properties of silver with other elements for clean, positive electrical contacting, pitting and burning are minimized for longer contact lifeArc chutes of heat absorbing, insulating material and metal grid plates quickly ''extinguish'' arcsUL listed lugs for copper or aluminum cable, at full frame rating, easy access and simple, straight in wiringProven reliabilityProvide cost effective solutionsMultiple types to fit in your application10 kA at 125 VDC, 10 kA at 480 VAC, 14 kA at 120/240 VAC, 14 kA at 240 VAC, 14 kA at 277 VAC interrupt rating
