Product Description

Siemens SIRIUS Varistor Surge Suppressor with LED 48–127V AC / 24–70V DC for 3RT2.1 & 3RH2 Contactors – 3RT2916-1JK00

Product Description

The Siemens 3RT2916-1JK00 is a genuine Siemens SIRIUS Varistor Surge Suppressor with LED designed for compatible Siemens 3RT2.1 contactors and 3RH2 auxiliary contactors. This contactor coil surge suppressor helps suppress voltage transients generated when an inductive contactor coil is switched, helping reduce electrical stress on the control circuit and supporting reliable operation of industrial automation systems. Siemens specifies this accessory for S00-size contactors.

The 3RT2916-1JK00 varistor surge suppressor supports 48–127V AC at 50/60Hz and 24–70V DC control supply voltage. Its varistor-based surge suppression helps limit switching-related voltage spikes, while the integrated LED provides visual indication of the control circuit. This makes it suitable for industrial motor control panels, automation systems, machine control panels, PLC applications, OEM equipment and electrical control cabinets.

Designed for convenient installation, the Siemens SIRIUS 3RT2916-1JK00 uses clip-on mounting and can be installed in any mounting position on compatible contactors. Siemens specifies an operating ambient temperature range of -25°C to +60°C and a storage temperature range of -40°C to +80°C. The product has a net weight of approximately 0.006 kg.

The Siemens 3RT2916-1JK00 surge suppressor is suitable for motor starter assemblies, Motor Control Centers (MCC), DOL motor starters, industrial automation panels, PLC-controlled machinery, OEM control cabinets, factory automation systems, electrical control panels and industrial switching applications using compatible Siemens 3RT2.1 or 3RH2 contactors.
