The coil connection uses spring-type terminals, which hold the wire under vibration better than screw clamps and reduce wiring time on the panel assembly line. ## Switching frequency limits per duty class The AC-3e rating also caps at 750 ops/h. These limits govern the application: a conveyor running continuous cycles stays within AC-3, while a crane hoist with frequent reversals must respect the AC-4 ceiling. The arcing time spans 4–15 ms at AC and 10–15 ms overall, a window that determines minimum clearance to adjacent components for arc quenching. ## Panel fit and thermal clearance These air gaps are needed for heat dissipation and arc quenching — crowding the contactor against other devices or the enclosure wall reduces the switching frequency ceiling and accelerates contact wear. Main contacts accept 20–12 AWG. The spring-type terminals on the coil side eliminate the need for screw tightening, reducing wiring time and the risk of loose connections under thermal cycling.","metaTitle":"Siemens 3RT2018-2AB01-ZW96 SIRIUS S00 Power Contactor, 10 A","metaDescription":"Siemens 3RT2018-2AB01-ZW96 SIRIUS S00 power contactor, 10 A at 24 V, spring-type terminals, DIN rail mount.
