The Siemens 3RT2926-1BB00 is a genuine Siemens SIRIUS Varistor Surge Suppressor designed for compatible Siemens 3RT2.2 contactors. This contactor coil surge suppressor helps limit voltage transients produced during switching of inductive contactor coils, reducing electrical stress on the control circuit and supporting reliable contactor operation. It is designed as a dedicated accessory for compatible S0-size 3RT2.2 contactors.
The 3RT2926-1BB00 varistor surge suppressor is suitable for control voltages of 24–48V AC at 50/60Hz and 24–70V DC. Its varistor-based suppression technology provides a practical solution for protecting control circuits from switching-related voltage spikes in industrial motor control panels, automation systems, machine control panels, OEM equipment, and electrical control cabinets.
Designed for convenient installation, the Siemens SIRIUS 3RT2926-1BB00 uses a compact clip-on mounting arrangement for compatible contactors. Its space-saving construction makes it suitable for applications where reliable contactor surge protection is required without adding significant panel space.
The Siemens 3RT2926-1BB00 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.
