Industrial plug-in power relays

The unique D-series power relay concept and the miniature C-series relays are specifically designed for heavy-duty applications, power-utilities, petrochemical industries, and mining.

High DC breaking capacity and inductive load switching offer long electrical life and low life-cycle costs.

The Solve-All™ relay application concept offers ultimate flexibility to design and supply tailor made D-series power relay products. Today the D-series power relays are used in its millions across the world.

  • High speed plug-in tripping relays

    High speed plug-in tripping relays

    Fast switching D-series relay with a trip time of < 7 ms. Suitable for demanding, critical applications.
  • Instantaneous plug-in Auxiliary power relays

    Instantaneous plug-in Auxiliary power relays

    Instantaneous power relays from Mors Smitt are designed for demanding applications such as power utilities, petro chemical industries and mining. The construction of the relay and choice of materials makes these power relays suitable to withstand corrosive atmospheres, low and high temperatures, vibration, in heavy duty environments. We offer the following power relay series for heavy duty applications; D series, heavy duty, power relays The D relays series are avaialble…
  • Latching / bistable heavy duty power relays

    Latching / bistable heavy duty power relays

    The voltage pulse will activate the relay to pull-in or release the contacts. The latching relay / bistable relay will hold its contactposition till the next voltage pulse. Below latching relays / bistable relays are designed for demanding heavy duty applications.
