SEL-351 / SEL-351S / SEL-351A — directional overcurrent protection and feeder automation
SEL-351, SEL-351S and SEL-351A are widely used directional overcurrent protection and automation terminals for feeders and lines. They operate in distribution and industrial networks and perform auto-reclosing, breaker failure protection and synchrophasor measurements.
- Functions
- directional overcurrent protection, four-shot auto-reclosing with synchronism check, breaker failure protection
- Communication
- Ethernet, Mirrored Bits
- Synchrophasors
- IEEE C37.118

Description
Four-shot auto-reclosing with synchronism check. Synchrophasors are sent per IEEE C37.118 over built-in Ethernet.
The Mirrored Bits channel carries discrete signals between terminals directly, without intermediate telecontrol. Optional power quality monitoring is available.
