Siemens SIRIUS 3RT2916-1LM00 Surge Suppressor Diode with LED, 24-70 V DC for Contactor S00 Original Brand New

Overview: Siemens SIRIUS 3RT2916-1LM00 Surge Suppressor

The Siemens SIRIUS 3RT2916-1LM00 is a premium, clip-on surge suppressor designed to protect DC-operated industrial control circuits from damaging voltage spikes. This essential accessory uses a suppression diode (or noise suppression diode) with an integrated LED for easy function monitoring and quick diagnostics.

Engineered specifically for the SIRIUS 3RT2.1 power contactors (Size S00) and 3RH2 auxiliary contactors, the 3RT2916-1LM00 ensures maximum equipment uptime and reliability. It effectively dampens switch-off voltage peaks (inductive kicks) that can prematurely age or damage sensitive control electronics and contactor coils.
