Description
XR351 Trip Circuit Supervision Relay
XR351 is an electro-mechanical relay for supervision and monitoring of a trip circuit, during both open and closed CB position, as well as for preclosing supervision. The XR351 has 3 attracted armature elements. It incorporates a time delay on de-energization, to keep the relay in an operated condition, during temporary reduction in the battery voltage.
Application
- Supervision and ensuring the integrity of the trip circuit of a breaker
- Continuous supervision, during both, open and closed position of circuit breaker
- Preclosing supervision to prevent circuit breaker from being closed where the trip relay has not been reset
Features
- Low burden
- Consistent positive action
- Complies with appropriate requirements of IEC 60255
- Epsilon draw-out case
