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 with up to 8 change over contacts (dpdt) no external retaining clip is needed due to an integrated ‘snap-lock’ that will keep the relay in its socket under all circumstances and mounting positions.
A wide variety of models and features are available to cover the most demanding applications.

C series, heavy duty, miniature power relays

The C-series miniature power relays can be used in both AC and DC voltage networks. These power relays are able to switch resistive and also inductive loads, depending on the options included. We offer instantaneous relays and safety/critical relay models.

400 series, heavy duty, power relays

The A400 and B400 relay series are designed for safety and/or critical applications. These power relays are standard equipped with double-make double-break contacts. The B400 relay series is also standard equipped with weld no transfer contacts (optional for the A400).
