The Siemens 3RT2926-1CD00 is a genuine Siemens SIRIUS RC Element Surge Suppressor designed for compatible Siemens 3RT2.2 contactors. This contactor coil surge suppressor helps limit voltage transients generated when an inductive contactor coil is switched, reducing electrical stress on the control circuit and supporting reliable contactor operation. Siemens specifies this accessory for S0-size 3RT2.2 contactors.
The 3RT2926-1CD00 RC surge suppressor supports 127–240V AC at 50/60Hz and 150–250V DC control supply voltage. Its RC element suppression technology is designed for compatible AC and DC contactor control circuits, making it suitable for industrial motor control, automation panels, machine control systems, OEM equipment, and electrical control applications.
Designed for convenient installation, the Siemens SIRIUS 3RT2926-1CD00 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 3RT2926-1CD00 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 3RT2.2 contactors.

The Siemens 3RT2926-1CD00 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 3RT2926-1CD00 supports 127–240V AC at both 50Hz and 60Hz.
This Siemens RC surge suppressor supports a 150–250V DC control supply voltage.
The 3RT2926-1CD00 is designed for Siemens SIRIUS 3RT2.2 contactors and is intended for S0 contactor size.
The 3RT2926-1CD00 uses an RC element for surge suppression. It is specified for AC/DC control supplies within its rated voltage ranges.
Yes. Siemens specifies the device for 127–240V AC at 50/60Hz and 150–250V 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 3RT2926-1CD00 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.
