Product Description


Siemens SIRIUS Diode Combination Surge Suppressor 12–250V DC for 3RT2.1 & 3RH2 Contactors – 3RT2916-1EH00

Product Description

The Siemens 3RT2916-1EH00 is a genuine Siemens SIRIUS Diode Combination Surge Suppressor designed for compatible Siemens 3RT2.1 contactors and 3RH2 auxiliary contactors. This contactor coil surge suppressor is designed to reduce voltage transients generated during switching of DC contactor coils, helping protect the control circuit and support reliable operation of industrial automation equipment. Siemens specifies this accessory for S00-size contactors.

The 3RT2916-1EH00 diode assembly is suitable for a wide 12–250V DC control supply voltage range. Its diode-combination suppression design helps reduce switching-related voltage spikes generated by inductive contactor coils, making it suitable for industrial motor control panels, automation systems, PLC-controlled machinery, machine control panels, OEM equipment and electrical control cabinets.

The Siemens SIRIUS 3RT2916-1EH00 features a compact design with clip-on mounting and can be installed in any mounting position on compatible contactors. The device measures 46 mm × 28 mm × 9 mm and has a net weight of approximately 0.006 kg. 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 3RT2916-1EH00 surge suppressor is suitable for motor starter assemblies, Motor Control Centers (MCC), DOL motor starters, industrial automation panels, PLC control systems, OEM control cabinets, factory automation systems, electrical control panels and industrial switching applications using compatible Siemens 3RT2.1 or 3RH2 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.
