The 1 NC auxiliary contact is built in, and the coil pulls in on 125 V DC. Spring-loaded terminals on the power and control sides speed panel wiring — no torque driver needed for the connection points. ## What the AC-3 rating means for your motor load At 4 kW / 400 V, this contactor handles a motor full-load current in the 8-9 A range. The DC coil (125 V) eliminates the inrush transformer and runs cooler than an AC coil on the same voltage; verify your control supply is DC, not rectified AC, because the hold characteristic differs.","metaTitle":"Siemens 3RT2016-2BG42-0CC0 Contactor, AC-3 4kW/400V, 1NC, S0","metaDescription":"Siemens 3RT2016-2BG42-0CC0 contactor, AC-3 rated 4kW at 400V, 1NC auxiliary, DC 125V coil, size S00 with spring-loaded terminals.
