The UC (universal current) coil accepts 220-240 V AC or DC, simplifying panel wiring where control voltage is mixed. Three main poles, size S6 frame with bar connections for high-current bus or cable terminations. Built-in auxiliary contacts: 2 NO + 2 NC, screw terminals. The conventional operating mechanical life is sized for frequent switching in pump, fan, and conveyor applications. ## Compliance RoHS compliance date listed as 04/24/2017, indicating the design meets EU substance restrictions from that date forward.","metaTitle":"Siemens 3RT5056-8AP38-0PR0 SIRIUS Power Contactor, 90 kW AC-","metaDescription":"Siemens SIRIUS 3RT5056-8AP38-0PR0 power contactor, 90 kW at 400 V AC-3, UC coil 220-240 V, 3-pole size S6, auxiliary contacts 2NO+2NC.
