The Hawkeye 40 Series combines a switching relay, a current status sensor, and a
Hand-Off-Auto (HOA) switch into a single nipple-mounted housing. The low voltage
and line voltage wires are electrically separated from each other. A hinged lid on the
low voltage side allows easy relay connection and trip point adjustment, while the
high voltage side is closed for added safety. The H40 is connected in series between
the power source and the motor device, and the relay and HOA switch control the on/
off functioning of the motor.
