Product Description

Siemens SIRIUS RC Surge Suppressor 24–48V AC / 24–70V DC for 3RT2.3 Contactors – 3RT2936-1CB00

Product Description

The Siemens 3RT2936-1CB00 is a genuine Siemens SIRIUS RC Element Surge Suppressor designed for compatible Siemens 3RT2.3 contactors. This compact contactor coil surge suppressor helps reduce voltage transients generated when an inductive contactor coil is switched, supporting reliable operation of control circuits and connected electrical components. Siemens specifies the accessory for S2-size 3RT2.3 contactors.

The 3RT2936-1CB00 RC surge suppressor supports 24–48V AC at 50/60Hz and 24–70V DC control supply voltages. Its RC-element design makes it suitable for compatible AC and DC contactor control circuits within the specified voltage ranges. This makes the accessory useful for industrial motor control panels, automation systems, machine control circuits, and OEM electrical panels.

Designed for easy installation, the Siemens SIRIUS 3RT2936-1CB00 uses clip-on mounting and can be installed in any mounting position. Its compact 30 × 30 × 15 mm dimensions help save panel space while providing a dedicated suppression solution for compatible SIRIUS contactors. 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 3RT2936-1CB00 surge suppressor is suitable for motor starter assemblies, Motor Control Centers (MCC), industrial automation panels, PLC-controlled machinery, factory automation systems, OEM control cabinets, electrical control panels, and industrial switching applications using compatible 3RT2.3 contactors.
