MSPR - Pilot Wire Intertrip Relays
The Actus MSPR-S Series intertrip SEND relay is used to interface trip circuit contacts, or other conventional protection relay contacts to the pilot wire with suitable electrical isolation for the feeder voltage level. The fast pick-up time (<8ms), ensures total intertrip time is kept to a minimum.
