Product Positioning

The 3RT1956-1CC00 is an RC surge suppressor suitable for Siemens SIRIUS series large contactors (S6, S10, S12 frames). It is compatible with coil voltage ranges of 48~127VAC or 70~150VDC. It is installed on the screw terminal of the operating mechanism and can effectively reduce the induced surge at the moment of coil release. It is a practical accessory to extend the life of control circuit components.

Core Product Advantages and Features

Medium voltage section coil applicable

This corresponds to a common medium-voltage coil voltage range of 48~127VAC/70~150VDC.

RC absorption principle

The induced surge at the moment the coil is de-energized is absorbed by a combination of resistors and capacitors.

Suitable for large frames

SIRIUS contactor operating mechanisms can be installed on S6, S10, and S12 frame structures.

Easy to install

Screw terminal connections allow for quick on-site installation or replacement.

Extend equipment life

Reduce the cumulative losses of surges to nearby relays and PLC output points.
