Siemens SIRIUS Varistor Surge Suppressor 24–48V AC / 24–70V DC for 3RT2.1 & 3RH2 Contactors – 3RT2916-1BB00

Product Description

The Siemens 3RT2916-1BB00 is a genuine Siemens SIRIUS Varistor Surge Suppressor designed for compatible 3RT2.1 contactors and 3RH2 auxiliary contactors. It is designed to suppress voltage transients generated during contactor coil switching, helping reduce electrical interference and support reliable operation of industrial control circuits. Siemens lists this product as an active PM300 product in its Surge Suppressors family.

The 3RT2916-1BB00 varistor surge suppressor supports 24–48V AC at 50/60Hz and 24–70V DC, making it suitable for both AC and DC contactor control applications. It is specifically designed for use with S00-size contactors and is suitable for Siemens SIRIUS contactor and auxiliary contactor applications.

Using varistor suppression technology, the accessory helps limit switching-related overvoltage and electrical interference produced by inductive contactor coils. This makes it suitable for applications such as industrial motor control panels, DOL starters, PLC control panels, automation systems, machine control cabinets, OEM panels and MCC applications.

The Siemens 3RT2916-1BB00 features clip-on mounting and can be installed in any mounting position. Its compact design makes it convenient for installation on compatible SIRIUS devices. Siemens specifies an operating temperature range of -25°C to +60°C and a storage temperature range of -40°C to +80°C. The product weight is approximately 6 g.

The Siemens 3RT2916-1BB00 is a suitable choice for panel builders, OEMs, automation professionals and maintenance teams requiring a reliable varistor-based contactor surge suppressor for compatible Siemens 3RT2.1 and 3RH2 devices.
