That makes it a natural fit for switching a three-phase load plus neutral, or for ganging four independent single-phase circuits that must all come on together. The body occupies 3 width units (a standard 18 mm per unit on DIN rail), so it takes up 54 mm of rail space. Depth is 71 mm, installation depth 64 mm, and height 90 mm — dimensions that fit standard 4- or 8-module distribution enclosures without crowding the gland plate. ## Protection and approvals No UL, CSA, or CE mark is listed in the spec record, but as a Siemens SENTRON product it typically carries CE marking for the European low-voltage directive; verify the specific approval marking on the unit if your project requires UL recognition.","metaTitle":"Siemens SENTRON 5TT5750-0 Insta Contactor, 63 A, 4 NO","metaDescription":"Siemens SENTRON 5TT5750-0 Insta contactor with 4 NO contacts, rated 63 A at 230 V AC, 440 V max.
