The NEMA size rating means the contactor is built to handle the inrush and thermal demands of motor loads up to that frame size — not just the thermal current, but the mechanical endurance for repeated starts. The NEMA 4 enclosure rating means the contactor body is sealed against hose-directed water and dust ingress, so it can sit in a washdown area or outdoor cabinet without an extra enclosure. ## What you need to wire it up The description explicitly notes you must add two terminal lug kits — the contactor ships without lugs. The 120 VAC coil pulls in on standard control voltage; the 600 V rated main poles handle 480 V and 600 V motor circuits common in North American panels. Wires up clean on a backplate or in a NEMA 4 enclosure — the NEMA 4 rating on the contactor itself means the panel builder can skip an extra enclosure in many washdown or outdoor spots.","metaTitle":"ABB A145N4-30-11-84 NEMA Size 4 Contactor, 135 A, 120 VAC","metaDescription":"ABB A145N4-30-11-84 NEMA Size 4 contactor, 135 A, 3-pole, 120 VAC coil, NEMA 4 rated.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Amps":"135","Type":"NEMA","Poles":"3","title":"A145N4-30-11-84","description":"135A, 3P, Contactor, NEMA 4, 120VAC|NEMA Size 4, 135 Amp, Non-Reversing Contactor, A-Line, 600V Rated, 3-Phase Magnetic, 120V AC Coil.
