It switches resistive and moderate inductive loads in panel-mounted control circuits, with a stated switching capacity of 2000 W for incandescent lamp loads. The 230 V AC coil actuation suits standard line-voltage control schemes. The 25 A AC-1 rating (resistive load) sets the continuous current limit per pole; for motor or inductive loads derate per the manufacturer's curve. The 440 V maximum across the contacts covers 400 V three-phase line-to-line, so it can switch a 400 V resistive load bank directly. The IP20 protection class means it's intended for dry, enclosed panel environments — no washdown or outdoor exposure. The manufacturer notes that spacers are required between units to ensure adequate heat dissipation; factor that into rail layout. Supplementary devices (auxiliary contact blocks, surge suppressors) can be installed on the side or top per the product extension capability.","metaTitle":"Siemens SENTRON 5TT5820-0 Insta Contactor, 4 NO, 25 A, 230 V","metaDescription":"Siemens SENTRON 5TT5820-0 Insta contactor, 4 NO contacts, rated 25 A at 230 V AC, 440 V max.
