It handles a rated voltage of 230 V AC and a maximum of 400 V, with a DC rated value of 220 V for the coil. The actuation voltage type is AC/DC, so it works with either supply. The contact arrangement — 2 NO and 2 NC — is fixed; no field-convertible poles. That matters if your circuit needs a different break/make count. The coil pulls 4 W per pole in hot operating state, so factor that into your panel heat budget. The manufacturer notes you must provide spacers between units for heat dissipation — don't pack them tight on the DIN rail without air gaps. At 3 modular width units (53.5 mm wide, 71 mm deep, 90 mm tall), it fits standard 18 mm-per-module DIN-rail spacing. The installation depth is 64 mm behind the panel face, so check your enclosure depth if you're retrofitting into a shallow box. The coil accepts AC or DC; rated coil voltage is 230 V AC, at DC it is rated 220 V.","metaTitle":"SENTRON 5TT5042-0 Insta Contactor, 2NO 2NC, 230V AC Coil","metaDescription":"SENTRON 5TT5042-0 insta contactor, 2 NO + 2 NC contacts, 230 V AC coil, 400 V rated, IP20, active production.
