Product details

The Siemens SIRIUS 3RT1916-1LN00-ZX90 is a surge suppressor — specifically an interference suppression diode with an integrated LED indicator — rated for 70 to 150 V DC. It's designed to snap onto S00-size contactors in the SIRIUS family, protecting the coil circuit from voltage spikes when the contactor de-energizes. The LED gives you a quick visual on coil status, handy during panel troubleshooting.
