Surge suppression for contactors Protects against voltage spikes For S00 size contactors Wide DC voltage range Reduces electrical noise

Product description

The Siemens 3RT1916-1DG00 is an interference suppression diode, also known as a surge suppressor, designed for use with Siemens contactors. It operates within a voltage range of 12 to 250V DC and is intended for mounting directly onto S00 size contactors to protect them from voltage spikes.

This component is crucial for extending the lifespan of contactors by mitigating electrical noise and transient overvoltages. It is commonly applied in motor control circuits, power switching, and general industrial control systems where contactor longevity is paramount.

Stanlo Automation, a veteran-owned surplus parts distributor, offers the Siemens 3RT1916-1DG00. While this is a phased-out product, we may have available stock for your critical applications. The preferred successor is the SIRIUS 3RT2916-1DG00.
