The Siemens 3RT2936-1BC00 is a genuine Siemens SIRIUS Varistor Surge Suppressor designed for compatible Siemens 3RT2.3 and 3RT2.4 contactors. This contactor coil surge suppressor helps limit voltage transients generated when an inductive contactor coil is switched, supporting reliable operation of control circuits and reducing electrical stress on connected components. The accessory is suitable for S2 and S3 contactor sizes.
The 3RT2936-1BC00 varistor surge suppressor supports 48–127V AC at 50/60Hz and 70–150V DC control supply voltage. Its varistor-based suppression technology makes it suitable for compatible AC and DC contactor control circuits within the specified voltage ranges, making it a practical accessory for industrial motor control, automation systems, electrical panels, machine control, and OEM applications.
Designed for convenient installation, the Siemens SIRIUS 3RT2936-1BC00 features clip-on mounting and can be installed in any mounting position on compatible contactors. Its compact construction, approximately 30 mm × 30 mm × 14.5 mm, helps 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 3RT2936-1BC00 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 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 3RT2936-1BC00 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 3RT2936-1BC00 supports 48–127V AC at both 50Hz and 60Hz.
The Siemens varistor surge suppressor supports a 70–150V DC control supply voltage.
The accessory is designed for Siemens SIRIUS 3RT2.3 and 3RT2.4 contactors and is suitable for S2 and S3 contactor sizes.
The 3RT2936-1BC00 uses a varistor as its surge suppression technology and is specified for AC/DC control supplies within its rated voltage ranges.
Yes. Siemens specifies the accessory for 48–127V AC at 50/60Hz and 70–150V DC, provided the compatible contactor coil and control supply are within the specified ranges.
The surge suppressor uses clip-on mounting and can be installed in any mounting position on a compatible Siemens SIRIUS contactor.
The Siemens data specifies approximately 30 mm width × 30 mm height × 14.5 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 3RT2936-1BC00 is a varistor surge suppressor accessory, not a complete contactor. It is designed for use with compatible Siemens SIRIUS 3RT2.3 and 3RT2.4 contactors.
SB Smart, Faridabad supplies genuine Siemens SIRIUS surge suppressors, contactors, overload relays, motor protection products, and industrial automation components with competitive pricing, GST invoices, technical support, bulk-order assistance, secure packaging, and delivery across Faridabad, Delhi NCR, and India.
