Siemens 3RT2916-1BC00 Surge Suppressor, Varistor for 48–127 V AC / 70–150 V DC Original Brand New

Overview

The Siemens 3RT2916-1BC00 is a highly effective, plug-in surge suppressor designed to protect the coils of specific Siemens SIRIUS industrial control devices from harmful voltage spikes. Utilizing varistor technology, this component safely absorbs and dissipates transient overvoltages, which are commonly generated when switching inductive loads (like contactor coils) off.

Its versatile operating voltage range makes it suitable for a wide variety of industrial applications, providing essential protection for 3RT2.1 power contactors and 3RH2 auxiliary contactors. By mitigating voltage surges, the 3RT2916-1BC00 significantly extends the operational lifespan of the contactor and protects sensitive upstream and parallel-connected electronic equipment in the control circuit.

Key Benefits

• Enhanced Equipment Protection: Prevents damage caused by voltage spikes and transient surges.

• Extended Component Life: Reduces coil stress and contact erosion for long-term reliability.
