  Alpha XR High reliability supervision relays

  The Alpha XR Series Relays are low burden electro-mechanical supervision relays for application on high security tripping and auxiliary supply circuits. The Alpha XR relays have been designed to provide a balance of low burden to minimize the possibility of circuit breaker mal-operation while maintaining a minimum contact whetting current to avoid nuisance alarm conditions. A key feature of the design is a high visibility flag indicator that can only…
