Alpha Auxiliary, Trip & Supervision Relays

The Alpha range is a new generation of electro-mechanical relays specifically designed for high voltage protection and control applications.

High performance and reliability remains paramount while production lead times have been reduced.

A wide voltage operating range and user selectable low or high burden tripping relay operation reduces the number of model variations.

The Alpha range is packaged in a draw out case system and can be either flush panel or rack mounted.

Application of the Alpha multi-contact high-speed trip relays ensures fast operation of less than 8 ms. The unique patented design and topology ensures minimal contact bounce.
