The front face is IP20, so it's safe for open-panel use with no additional cover. ## Contact ratings and wiring The 10 A rating at 24 V is the highest thermal current; at 110 V the rating drops to 1 A, and at 690 V it's 1 A. For AC-15 switching (solenoid valves, contactor coils), the 50 Hz make/break ratio is 0.8–1.1 at rated voltage. Shock resistance is 10g for 5 ms and 5g for 10 ms.","metaTitle":"Siemens 3RH1131-2GG20 SIRIUS Auxiliary Contactor, S00, 3 NO","metaDescription":"Siemens 3RH1131-2GG20 SIRIUS auxiliary contactor, size S00, 3 NO + 1 NC contacts, rated 10 A at 24 V.
