350 A amperage rating provides robust protection for heavy-load feeders. The business impact is improved fault isolation and reduced nuisance trips, lowering unplanned downtime in manufacturing and processing lines. Application: motor control centers and power distribution panels where large currents are routine. Four-pole LG frame enables true four-wire, three-phase protection. This improves phase balance and simplifies coordination with upstream devices. Application: panelboards and MCCs in high-demand environments such as packaging and metals processing. High interrupt ratings—200 kAIC at 240 Vac, 150 kAIC at 480 Vac, 65 kAIC at 600 Vac—offer strong short-circuit protection. The benefit is faster fault clearance and reduced equipment damage, lowering maintenance costs. Application: large motors and conveyors in continuous-operation facilities. UL Listed, CSA Certified, IEC Rated with HACR compatibility ensures global acceptance and compliance. This minimizes rework for international projects and supports risk-managed deployments. Application: global plants and multi-region projects. Line and load terminals with metric mounting simplify installation; compact 4.09 in depth and 7.22 in height/width keep panel space efficient. Weight is 15.7 lb, aiding transport and installation planning. Warranty coverage includes 1 year from installation or 18 months from shipment, whichever occurs first.
