At 480 V it carries 96 A; at 600 V it carries 77 A. For North American ratings: 30 hp at 200/208 V and 220/230 V, and 75 hp at 460/480 V and 575/600 V. The AC-4 rating at 400 V is also 45 kW — useful for reversing or inching applications where the contactor makes and breaks motor current under load.","metaTitle":"Siemens 3RA2346-8XB30-1AL2 SIRIUS Reversing Contactor","metaDescription":"Siemens 3RA2346-8XB30-1AL2 SIRIUS reversing contactor assembly, 45 kW at 400 V AC-3, 96 A at 480 V.
