The Siemens 3RT2926-1CB00 is a genuine Siemens SIRIUS RC Element Surge Suppressor designed for compatible Siemens 3RT2.2 contactors. This contactor coil surge suppressor is used to reduce voltage transients generated during switching of inductive contactor coils, helping protect the control circuit and improve the reliability of contactor operation. Siemens specifies this accessory for S0-size 3RT2.2 contactors.
The 3RT2926-1CB00 RC surge suppressor supports a 24–48V AC control supply at 50/60Hz and a 24–70V DC control supply. Its RC-element design makes it suitable for compatible AC and DC contactor control circuits used in industrial motor control, automation panels, machine control systems, OEM equipment, and electrical control panels.
The Siemens 3RT2926-1CB00 features a compact clip-on mounting design and can be installed in any mounting position on compatible contactors. With dimensions of 19 mm height × 30 mm width × 12 mm depth and a net weight of approximately 5 g, it is designed for space-efficient installation inside industrial control panels.
The 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, and industrial switching applications using compatible Siemens 3RT2.2 contactors.
At SB Smart, Faridabad, we supply genuine Siemens SIRIUS surge suppressors, contactors, overload relays, motor protection devices, soft starters, MCCBs, MCBs, and industrial automation products with competitive pricing, GST invoices, technical support, bulk-order assistance, secure packaging, and delivery across Faridabad, Delhi NCR, and major cities throughout India.

The Siemens 3RT2926-1CB00 is an RC element surge suppressor used with compatible Siemens SIRIUS 3RT2.2 contactors to help suppress voltage transients associated with contactor coil switching.
The 3RT2926-1CB00 supports 24–48V AC at both 50Hz and 60Hz.
This Siemens RC surge suppressor supports a 24–70V DC control supply voltage.
The 3RT2926-1CB00 is designed for compatible Siemens SIRIUS 3RT2.2 contactors and is specified for S0 contactor size.
The 3RT2926-1CB00 uses an RC element for surge suppression and is designed for AC/DC control supplies within its specified voltage ranges.
Yes. Siemens specifies the device for 24–48V AC at 50/60Hz and 24–70V DC, provided the compatible 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 3RT2926-1CB00 is an RC element surge suppressor accessory, not a complete contactor. It is designed for use with compatible Siemens SIRIUS 3RT2.2 contactors.
SB Smart, Faridabad supplies genuine Siemens SIRIUS surge suppressors, contactors, overload relays, motor protection products, auxiliary accessories, and industrial automation components with competitive pricing, GST invoices, technical support, bulk-order assistance, secure packaging, and delivery across Faridabad, Delhi NCR, and India.
