The 230 V AC coil means it pulls in on a standard control voltage — no separate DC supply needed for the magnet, which simplifies the control transformer spec in a panel. ## Contact arrangement and panel fit Two normally-open and two normally-closed auxiliary contacts are built in — that covers feedback to a PLC and a hold-in circuit without an add-on block. The housing is IP20, so it is touch-safe once installed in an enclosure but not rated for washdown — keep it behind a panel door. At 71 mm deep, 54 mm wide, and 90 mm tall, it occupies 3 modular width units on a DIN rail — plan your rail space accordingly. ## Installation note — spacers required The manufacturer explicitly requires spacers between units for heat dissipation — do not gang them tight on the rail or the contactor will run hot and may nuisance-trip or weld contacts.","metaTitle":"Siemens 5TT5852-0 SENTRON Insta Contactor, 63 A, 440 V","metaDescription":"Siemens 5TT5852-0 SENTRON insta contactor, 63 A at 440 V AC, 2 NO + 2 NC contacts, IP20, 3 MW.
