The Siemens 3RT2936-1BE00 is a genuine Siemens SIRIUS Varistor Surge Suppressor designed for compatible 3RT2.3 and 3RT2.4 contactors. This contactor coil surge suppressor helps limit voltage transients generated when an inductive contactor coil is switched off, supporting reliable operation of control circuits and reducing electrical stress on connected components. Siemens specifies this accessory for S2 and S3 contactor sizes.
The 3RT2936-1BE00 varistor surge suppressor is designed for 240–400V AC control voltage at 50/60Hz. Its varistor-based suppression technology is suitable for AC contactor coils within the specified voltage range and makes it a practical accessory for industrial motor control, automation systems, electrical panels, and machine control applications.
Designed for convenient installation, the Siemens SIRIUS 3RT2936-1BE00 uses clip-on mounting and can be installed in any mounting position on the compatible contactor. Its compact 30 × 30 × 15 mm dimensions 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 3RT2936-1BE00 surge suppressor is suitable for motor starter assemblies, Motor Control Centers (MCC), industrial automation panels, PLC-controlled machinery, OEM control cabinets, factory automation systems, electrical control panels, and industrial switching applications using compatible SIRIUS 3RT2.3 or 3RT2.4 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 3RT2936-1BE00 is a varistor surge suppressor used with compatible Siemens SIRIUS 3RT2.3 and 3RT2.4 contactors to help suppress voltage transients generated during contactor coil switching.
The 3RT2936-1BE00 is designed for 240–400V AC control supply voltage at 50Hz and 60Hz.
The accessory is designed for Siemens SIRIUS 3RT2.3 and 3RT2.4 contactors and is suitable for S2 and S3 contactor sizes.
The 3RT2936-1BE00 uses a varistor as its surge suppression technology.
The surge suppressor uses clip-on mounting and can be installed in any mounting position on a compatible SIRIUS contactor.
No. The 3RT2936-1BE00 is specified for 240–400V AC control supply at 50/60Hz. For DC coils, a suitable Siemens surge suppressor designed for the required DC voltage range should be selected.
The specified dimensions are approximately 30 mm height × 30 mm width × 15 mm depth.
Siemens specifies an operating ambient temperature range of -25°C to +60°C and a storage temperature range of -40°C to +80°C.
No. The 3RT2936-1BE00 is a varistor surge suppressor accessory, not a complete contactor. It is installed with compatible Siemens SIRIUS 3RT2.3 or 3RT2.4 contactors.
