The contact arrangement is 3 normally-open and 1 normally-closed pole, giving you a dedicated NC auxiliary for status feedback or interlocking without adding a side-mount block. ## Coil voltage and control compatibility The coil is rated 230 V AC (220 V DC), matching standard European lighting-circuit control voltages. The AC coil draws from the same phase as the load in most panel layouts, simplifying the control transformer count. Maximum rated voltage across the main poles is 400 V, consistent with 3-phase 400 V line-to-line systems. The contactor fits into a 3-module-width (53.5 mm) DIN-rail footprint, occupying three 18 mm slots in a distribution board. Sourced to order against your BOM quantity.","metaTitle":"Siemens 5TT5041-0 SENTRON Insta Contactor, 40 A, 3 NO + 1 NC","metaDescription":"Siemens 5TT5041-0 SENTRON insta contactor, 40 A rated current, 230 V AC coil, 3 NO + 1 NC contacts, 3 MW.
