The coil accepts both AC and DC control voltage at 24 V (rated value), giving flexibility for either a 24 VDC PLC output or a 24 VAC control transformer without swapping the contactor. ## DIN Rail Fit and Panel Integration The body measures 90 mm tall, 53.5 mm wide, and 71 mm deep, with an installation depth of 64 mm — it snaps onto standard DIN rail and occupies 3 modular width units (each ~18 mm), leaving room for adjacent breakers or terminals in a crowded enclosure. Siemens specifies that spacers must be provided between units to ensure heat dissipation — at 8 W per pole in hot operating state, the contactor needs airflow or physical gap to keep the enclosure from baking adjacent components. IP20 rated — finger-safe from the front but not sealed against dust ingress; mount it inside a panel or enclosure, not exposed to washdown or outdoor weather. ## Active Production and Sourcing Available through independent distribution channels; quoted to order against the BOM quantity. Volume pricing and lead time confirmed at RFQ — no stock-holding claim, sourced per the buyer's quantity and delivery window.","metaTitle":"Siemens 5TT5050-2 SENTRON Insta Contactor, 4 NO, 63A, 400V","metaDescription":"Siemens 5TT5050-2 SENTRON insta contactor, 4 NO contacts, rated 63 A at 400 V AC, 24 V AC/DC coil, IP20, 3 MW.
