The S00 footprint — 45 mm wide, 57.5 mm tall, 72 mm deep — fits the standard SIRIUS grid; it occupies one 45 mm slot on the rail. ## Wiring and contact ratings Terminals accept solid conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm². At 110 V the contact current is 1 A; at 220 V it drops to 0.27 A, and at 500 V to 2 A — the non-linear derating reflects the arc extinction capability at higher voltages. Shock resistance is 10g / 5 ms and 5g / 10 ms, adequate for most industrial machinery but not for high-vibration mobile equipment without additional support.","metaTitle":"Siemens 3RH1140-1AP60 SIRIUS Auxiliary Contactor, 4 NO, S00,","metaDescription":"Siemens 3RH1140-1AP60 SIRIUS auxiliary contactor, size S00, 4 NO instantaneous contacts, rated 10 A at 24 V.
