Rated for 0.5–52 A at 480/277 Vac and 360/180 Vdc, AS168X Series limits let-through energy in event of short circuit up to 10 kA at 277 Vac. Series offers 3 levels of short circuit protection, categorized by F/DF Trip for resistive loads, G/DG for slightly inductive loads, and H/DH Trip for highly inductive loads. Thermal magnetic, positively trip-free breakers, with manual ON/OFF actuation deliver 6,000 cycles. Available from 1–4 poles, DIN rail-mountable units operate from -20 to +60°C.
