That 6 mm side gap is the tightest — adjacent contactors or other devices need that much air or an insulating barrier. The magnet coil uses screw-type terminals, so no special crimp tool is needed for the coil wiring. Arcing time is listed as 10 ms, which is short enough that arc flash coordination with upstream breakers is straightforward.","metaTitle":"Siemens 3RT2025-1AP00 SIRIUS Power Contactor, Size S0, 45mm","metaDescription":"Siemens 3RT2025-1AP00 SIRIUS power contactor, Size S0, 45mm width, screw-type terminals, auxiliary switch included.
