Product Description

Siemens SIRIUS RC Surge Suppressor 24–48V AC / 24–70V DC for 3RT2.2 Contactors – 3RT2926-1CB00

Product Description

The Siemens 3RT2926-1CB00 is a genuine Siemens SIRIUS RC Element Surge Suppressor designed for compatible Siemens 3RT2.2 contactors. This contactor coil surge suppressor is used to reduce voltage transients generated during switching of inductive contactor coils, helping protect the control circuit and improve the reliability of contactor operation. Siemens specifies this accessory for S0-size 3RT2.2 contactors.

The 3RT2926-1CB00 RC surge suppressor supports a 24–48V AC control supply at 50/60Hz and a 24–70V DC control supply. Its RC-element design makes it suitable for compatible AC and DC contactor control circuits used in industrial motor control, automation panels, machine control systems, OEM equipment, and electrical control panels.

The Siemens 3RT2926-1CB00 features a compact clip-on mounting design and can be installed in any mounting position on compatible contactors. With dimensions of 19 mm height × 30 mm width × 12 mm depth and a net weight of approximately 5 g, it is designed for space-efficient installation inside industrial control panels.

The 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.
