The SEL-351S Relay provides wide-area system stability awareness with IEEE C37.118 synchrophasors and simplifies communications with built-in Ethernet The 351A relays are for feeder protection and the 351S relays serve as main secondary breakers Large, easy-to-use operator controls and optional independent SafeLock trip/close pushbuttons enhance operation and simplify panels.
Feeder Protection. The SEL-351 Relay has built-in Ethernet and IEEE C37.118 synchrophasors, and is ideal for directional overcurrent applications The SEL-351S Relay is a protection and breaker control device that integrates overcurrent, directional, and reclosing elements with SELogic control and metering functions
SEL351S Schweitzer 0351S6X9D3J5421 SEL351S Protection System. The SEL SEL-351S Protection and Breaker Control Relay includes a robust set of phase, negative-sequence, residual, and neutral overcurrent elements If older SEL-351S relays (with firmware revisions R102 through R107) are upgraded to R108 (or higher) firmware, they too can be wye connected or delta connected, provided that the voltage rating is not exceeded
