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.

Delta XRD Models
XRD-4 Trip supply supervision with hand-reset mechanical flag alarm indication and 4 change over alarm contacts
XRD-5 Trip supply supervision with self-reset LED alarm indication and 2 change over alarm contacts
XRD-6 Trip circuit supervision with hand reset mechanical flag alarm indication and 3 change over alarm contacts
XRD-7 Trip circuit supervision with self-reset LED alarm indication and 2 change over alarm contacts

The Delta range is packaged in a size 2, 2U high case that may be flush panel, rack or rail mounted.

A plug in terminal block is provided to allow panel pre-wiring.
