DC Control 146 Field Loss Relay
Series 146 Relays provide excellent protection against overspeeding on
DC shunt or compound wound motors in the event of an open circuit in the
field. The relay coil is connected in series with the shunt field while the re-lay
motor contacts are in the motor control circuit. The relay coil is de-energized
if the field opens and the relay contacts open to disconnect the motor from
line. Where shunt or compound wound motors are operated at light loads or
not rigidly connected to the load, field loss relays provide protection against
motor and load damage from overspeeding. The Series 146 Relay is a UL
recognized component.
Coils are designed to carry maximum field current continuously. Relays are
factory adjusted to pick-up at one tenth of the maximum field current amps.
listed. Drop-out is approximately 62% of the pick-up value. Other pick-up
values on special order.
