That voltage-dependent rating is standard for DC switching: the same contact set handles higher currents at lower voltages, lower currents at higher voltages. The 13 W closing power on the DC coil tells you the magnet is sized for reliable pull-in even on a weak 24 VDC supply — useful if the panel has a long cable run to the power supply. That means you can orient the contactor to match the wiring ducts without fighting the latch. The 57.5 mm height and 90 mm width keep it within the S00 footprint, leaving room alongside the main contactor it follows.","metaTitle":"Siemens 3RH2431-1LW80-0LA0 SIRIUS Auxiliary Contactor","metaDescription":"Siemens 3RH2431-1LW80-0LA0 SIRIUS auxiliary contactor, size S00, 3 instantaneous NO contacts.
