Phase Sequence Relay BA9041

Phase Sequence Relay BA9041

The phase sequence relays BA 9041 an AI 941N monitor the right order of the phases in a 3-phase system.

Function:

When all 3 phases are connected to the device and the phase sequence is correct, the output contacts are activated, 11-14 and 21-24 close and a green LED comes on.

When the voltage in one phase drops below 60% of the nominal voltage the relay is de-energized.
