The Siemens 3RT2926-1JK00 is a genuine Siemens SIRIUS Varistor Surge Suppressor with LED designed for compatible Siemens 3RT2.2 contactors. This contactor coil surge suppressor helps limit voltage transients generated when an inductive contactor coil is switched, helping reduce electrical stress on the control circuit and supporting reliable contactor operation. Siemens specifies this accessory for S0-size 3RT2.2 contactors.
The 3RT2926-1JK00 varistor surge suppressor supports 48–127V AC at 50/60Hz and 24–70V DC control supply voltage. Its varistor-based surge suppression with integrated LED indication makes it suitable for compatible AC and DC contactor control circuits in industrial motor control, automation panels, machine control systems, OEM equipment, and electrical control applications.
Designed for easy installation, the Siemens SIRIUS 3RT2926-1JK00 uses clip-on mounting and can be installed in any mounting position on compatible contactors. Its compact dimensions of 19 mm × 30 mm × 12 mm help save valuable control-panel space. 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 Siemens 3RT2926-1JK00 surge suppressor is suitable for motor starter assemblies, Motor Control Centers (MCC), industrial automation panels, PLC-controlled machinery, DOL motor starters, OEM control cabinets, factory automation systems, electrical control panels, and industrial switching applications using compatible 3RT2.2 contactors.

The Siemens 3RT2926-1JK00 is a varistor surge suppressor with LED used with compatible Siemens SIRIUS 3RT2.2 contactors to help suppress voltage transients associated with contactor coil switching.
The 3RT2926-1JK00 supports 48–127V AC at both 50Hz and 60Hz.
This Siemens varistor surge suppressor supports a 24–70V DC control supply voltage.
The 3RT2926-1JK00 is designed for Siemens SIRIUS 3RT2.2 contactors and is intended for S0 contactor size.
The 3RT2926-1JK00 uses a varistor for surge suppression and includes an integrated LED for visual indication.
Yes. Siemens specifies the device for 48–127V AC at 50/60Hz and 24–70V DC, provided the contactor and control circuit are within the specified voltage ranges.
The surge suppressor uses clip-on mounting and can be installed in any mounting position on the compatible contactor.
The specified dimensions are 19 mm height × 30 mm width × 12 mm depth.
The specified operating ambient temperature range is -25°C to +60°C, while the storage temperature range is -40°C to +80°C.
No. The 3RT2926-1JK00 is a varistor surge suppressor accessory with LED, not a complete contactor. It is designed for use with compatible Siemens SIRIUS 3RT2.2 contactors.
Manufactured according to Siemens quality standards and carrying CE, UL, and CSA approvals, the 3RT2926-1JK00 Varistor with LED delivers dependable long-term performance and seamless compatibility with Siemens SIRIUS motor control products.
