Protective relay

OverviewOperation principlesTypes according to constructionRelays by functionsPower source

In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected. The first protective relays were electromagnetic devices, relying on coils operating on moving parts to provide detection of abnormal operating conditions such as over-current, overvoltage, reverse power flow, over-frequency, and under-frequency.

SLB/SLB-1 breaker pole failure relay

The SLB relay protects against breaker pole failure, i.e. pole disagreement. Pole failure is defined as having one or more breaker poles open, while one or more poles are closed, during non fault

SB Latching relay

The SB is a latching safety critical relay with 2 stable magnetically latched states. When 1 coil is energized, the relay actuates from magnetically latched position 1 to 2.
