The coil is 24 V AC/DC, so it works on either supply without needing a separate rectifier or relay. The 40 A rating means it handles motor loads, resistive heating, or lighting banks up to that current — for filament lamp loads the switching capacity is 3000 W, which covers a decent string of high-bay fixtures. This contactor is a 3-module-wide unit (54 mm) that snaps onto standard DIN rail. Depth is 71 mm, installation depth 64 mm, so it clears most 80 mm deep enclosures.","metaTitle":"Siemens 5TT5741-2 SENTRON Insta Contactor, 40 A, 3 NO 1 NC,","metaDescription":"Siemens 5TT5741-2 SENTRON Insta contactor, 40 A rated, 3 NO + 1 NC contacts, 24 V AC/DC coil.
