The Delta XR Series Relays are low burden electro-mechanical supervision relays for application on high security tripping and auxiliary supply circuits.
The Delta XR relays have been designed to provide a balance of low burden to minimize the possibility of circuit breaker maloperation while maintaining a minimum contact whetting current to avoid nuisance alarm conditions.
