Motor-rated contactor for S00 panel builds
The Siemens 3RT2018-2AP02-Z W97 is a size S00 power contactor from the SIRIUS 3RT2 family, rated for AC-3e/AC-3 duty at 16 A and 7.5 kW at 400 V. That AC-3e rating means it's designed for switching three-phase squirrel-cage motors — the 'e' suffix indicates enhanced electrical endurance for higher switching frequencies typical in conveyor or pump cycling. The 230 V AC coil at 50/60 Hz is a standard control voltage across European panel designs, so it drops straight into an existing 230 V control transformer circuit without a separate power supply.
Spring-loaded terminals and auxiliary contact
Termination is spring-loaded (cage clamp), which speeds up panel wiring compared to screw terminals — no torque driver needed, just strip and insert. The integrated 1 NC auxiliary contact gives you a feedback signal for the PLC or a safety chain without adding a separate aux block. On size S00, the contactor footprint is compact enough for dense DIN-rail layouts; the 75 x 70 x 45 mm package dimensions confirm it fits standard 35 mm rail with room for adjacent overload relays or busbars.
