Product Description

Siemens SIRIUS RC Surge Suppressor 48–127V AC / 70–150V DC for 3RT2.4 Contactors – 3RT2946-1CC00

Product Description

The Siemens 3RT2946-1CC00 is a genuine Siemens SIRIUS RC Surge Suppressor designed to reduce switching voltage peaks generated by contactor coils. This RC element surge suppressor is specifically designed for use with Siemens SIRIUS 3RT2.4 contactors and operates with 48–127V AC at 50/60Hz or 70–150V DC control voltage.

The 3RT2946-1CC00 surge suppressor helps protect control circuits and connected electrical components from transient voltage peaks that can occur when an inductive contactor coil is switched off. By suppressing these switching transients, the RC element can help improve electromagnetic compatibility and contribute to reliable operation of industrial contactor control systems.

Designed for SIRIUS 3RT2.4 contactors, this accessory has a Size S3 design and is intended for convenient attachment to the compatible contactor. Siemens specifies clip-on mounting, making installation straightforward during contactor assembly or maintenance.

The Siemens 3RT2946-1CC00 RC element is suitable for industrial motor control panels, contactor assemblies, Motor Control Centers (MCC), machine automation systems, OEM control panels, factory automation equipment, and electrical control cabinets where compatible 3RT2.4 contactors are installed.
