Rated surge voltage withstand of 6 kV and IP20 finger-safe front make it suitable for standard industrial control panels. ## Contact configuration and switching reliability Three NO contacts with zero NC, zero delayed, zero lagging, and zero make-before-break — a clean, simple set for adding extra control-circuit inputs or interlocking where only make contacts are needed. Fastening method is screw and snap-on mounting — the DIN-rail clip is standard, and the screw holes give a backup for vibration-prone installs. Shock resistance 10g / 5 ms and 5g / 10 ms; pollution degree 3 (conductive pollution or dry non-conductive that becomes conductive). ## Switching capacity across voltages Rated operational currents vary by voltage and frequency: at 24 V it switches 10 A, at 110 V 1 A, at 220 V 0.27 A, at 230 V 6 A, at 400 V 3 A, at 500 V 2 A, and at 690 V 1 A. The 50/60 Hz frequency split shows a slight derating at 60 Hz (0.85 to 1.1 vs 0.8 to 1.1 at 50 Hz). For a 24 VDC control circuit, the 10 A rating gives generous headroom for pilot-duty loads.","metaTitle":"Siemens 3RH1131-1AE00 SIRIUS Auxiliary Contactor, 3 NO, 45 m","metaDescription":"Siemens 3RH1131-1AE00 SIRIUS auxiliary contactor, size S00, 3 NO contacts, 45 mm width, screw/snap-on mounting, IP20 front.
