It covers a control supply voltage range of 12 to 250 V DC, making it suitable for most standard 24 VDC, 48 VDC, 110 VDC, and 220 VDC coil circuits found in industrial panels. ## What It Does and Where It Mounts The suppressor clips directly onto the coil terminals of a SIRIUS Size S00 contactor. The diode provides a path for the inductive flyback current when the coil de-energizes, preventing voltage spikes that could damage PLC outputs or other control electronics. It is a standard accessory for any DC-operated S00 contactor in a control panel.","metaTitle":"Siemens 3RT1916-1DG00 SIRIUS Surge Suppressor, DC 12-250V","metaDescription":"Siemens 3RT1916-1DG00 SIRIUS surge suppressor with diode for DC coils, 12-250V.
