Breaker Failure Relay and Monitor
Description: Breaker failure relay, circuit breaker monitor.
Application:The SEL-2BFR Relay performs circuit breaker protective functions. Breaker failure relaying, diagnostics, and data recording are included. It has several logic schemes for circuit breaker failure detection.
- Detects failure to interrupt fault, load, or line-charging currents
- Apply to single-breaker, ring-bus, and breaker-and-a half installations
- Operates in single- or three-pole trip schemes
- Thermal models protect, trip, and close resistors
- Detects current unbalance when one or two poles fail to close
- Provides detailed breaker operation data with 15-cycle event reports
- Stores 100 breaker operation summaries
- Programmable mask logic for flexible application and testing
- Serial communication ports allow local or remote interaction with the relay
