The 24 VDC coil draws 3.2 W during both closing and holding, so the power supply must sustain that continuous draw without droop. Contact ratings vary by voltage: at 24 V it switches 10 A, at 110 V it switches 1 A, at 230 V it switches 6 A, at 400 V it switches 3 A, at 500 V it switches 2 A, and at 690 V it switches 1 A. The 60 V rated value entry likely refers to the coil's rated control supply voltage, not the contact rating. Mechanical life is typical 5 million operations. Dimensions are 90 mm wide, 57.5 mm high, and 72 mm deep — the S00 footprint common across the SIRIUS family. Shock resistance is 10g at 5 ms and 5g at 10 ms. Terminal capacity accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid, with AWG equivalents of 2x (20 to 16), 2x (18 to 14), or 1x 12. This covers most control wiring gauges used in panel building. RoHS compliance date is noted as July 1, 2006, indicating the part meets EU RoHS requirements. The product extension for auxiliary switch is marked as yes, meaning add-on auxiliary contact blocks are available.","metaTitle":"Siemens 3RH1422-1BE40 SIRIUS Auxiliary Contactor, S00, 24 VD","metaDescription":"Siemens 3RH1422-1BE40 SIRIUS auxiliary contactor, size S00, 4-pole (2 NO + 2 NC), 24 VDC coil, screw/snap-on mount, IP20.
