The coil accepts both AC and DC actuation, with a rated coil voltage of 230 V AC or 220 V DC. The 24 A rating means this contactor can handle motor loads, resistive heaters, or lighting circuits up to that current — but with four NC contacts, it's wired to break a circuit when the coil is energized, not make it. Think of it as a safety interlock or a normally-closed isolation path that opens on command. The 1 500 W filament lamp switching capacity gives a practical limit for incandescent lighting banks. Depth is 71 mm, with an installation depth of 64 mm — that's the space behind the panel face. Height is 90 mm. IP20 finger-safe protection means it's suited for enclosed control panels where incidental contact is prevented by the enclosure door.","metaTitle":"Siemens 5TT5733-0 SENTRON Insta Contactor, 4 NC, 24 A, 230 V","metaDescription":"Siemens 5TT5733-0 SENTRON Insta contactor, 4 NC contacts, rated 24 A at 230 V AC, 440 V max switching, IP20, 36 mm wide.
