It's designed to clip onto 3RT2.1 power contactors and 3RH2 auxiliary contactors, knocking down the inductive kick from the DC coil when it de-energizes. That LED gives you a quick visual on whether the coil circuit is live, which saves a meter pull on a crowded panel. ## Voltage range and what it means on the line Rated for 70 to 150 V DC, this diode handles the common control voltages you see across European and North American DC coil circuits — 110 VDC, 125 VDC, nominal 120 VDC. The LED lights across that whole band, so you're not guessing whether the suppression is active. Below 70 V the diode won't break over cleanly; above 150 V you risk avalanche failure. Keep the coil voltage inside that window. Clip-on fastening method, no screws, no DIN-rail footprint of its own — it snaps directly onto the contactor's coil terminals. That means zero added panel width. The suppressor itself measures 28 mm wide by 46 mm tall by just 9 mm deep, so it sits flush against the contactor face. ## Environmental limits for the route No IP rating is listed on this component; it relies on the contactor's enclosure for protection against dust and moisture.","metaTitle":"Siemens 3RT2916-1LN00 SIRIUS Surge Suppressor, Diode, 70-150","metaDescription":"Siemens 3RT2916-1LN00 SIRIUS surge suppressor with suppression diode and LED, rated 70-150 V DC for S00 contactors.
