Product Description

Siemens SIRIUS RC Surge Suppressor 48–127V AC / 70–150V DC for 3RT2.3 Contactors – 3RT2936-1CC00

Product Description

The Siemens 3RT2936-1CC00 is a genuine Siemens SIRIUS RC Element Surge Suppressor designed for compatible 3RT2.3 contactors. This contactor coil surge suppressor helps reduce voltage transients generated when an inductive contactor coil is switched off, supporting reliable operation of control circuits and connected electrical components. Siemens specifies this accessory for S2-size 3RT2.3 contactors.

The 3RT2936-1CC00 RC surge suppressor supports a control supply voltage of 48–127V AC at 50/60Hz and 70–150V DC. Its RC-element design is suitable for both AC and DC control supplies within the specified voltage ranges, making it a practical accessory for industrial motor control and automation applications.

This Siemens SIRIUS surge suppressor uses clip-on mounting, allowing convenient installation on compatible contactors. With a compact size of approximately 30 × 30 × 15 mm, it is well suited for industrial control panels where reliable coil suppression and efficient use of panel space are important. Siemens specifies an operating ambient temperature range of -25°C to +60°C.

The Siemens 3RT2936-1CC00 is suitable for motor starter assemblies, Motor Control Centers (MCC), industrial automation panels, PLC-controlled machinery, OEM control cabinets, factory automation systems, and electrical control panels using compatible 3RT2.3 contactors.
