These ratings cover the typical control-voltage levels found in industrial panels — 24 V for PLC-driven circuits, 230/400 V for motor contactor coils, and 690 V for higher-voltage auxiliary circuits. ## Mounting & Panel Fit The 45 mm width and 72 mm depth fit the S00 footprint, common in compact control panels. Installation altitude is limited to 2 000 m above sea level. ## Environmental & Protection Operating temperature range is -10 to +55 °C; storage from -25 to +70 °C. Shock resistance: 15g / 5 ms sine pulse, 10g / 5 ms rectangular impulse.","metaTitle":"Siemens 3RH7140-1AB00 SIRIUS Contactor Relay, 4 NO, AC Coil,","metaDescription":"Siemens SIRIUS contactor relay 3RH7140-1AB00, 4 NO contacts, AC coil, Size S00, 45 mm width, IP20 front.
