Internal Current Sensing (for single-phase loads)
Models with internal current-sensing are great for direct-control and current-sensing of
exhaust fans, pumps, and other single-phase electrical loads up to 20A. The control relay
contacts of these models wire directly in series with single-phase motors using the wires
that exit the housing through the 1/2" conduit hub. The current of the load is sensed within
the housing. Low-voltage wiring from the controller for the control relay coil and status
switch enter the separate Class 2 wiring compartment in the housing through star bushings
or conduit and are connected to screw terminals.
Remote Current Sensing (for loads with motor starters)
Models with remote current-sensing are great for control and status sensing of electrical
loads that require a motor starter. The control relay contacts of these models are wired
in series with the motor starter coil using the two wires that exit the housing through the
1/2'' conduit hub. Currents up to 150A are sensed externally with a current sensing ring
connected to the two gray wires that also exit through the 1/2'' conduit hub. Low-voltage
wiring from the controller for the control relay coil and status switch enter the separate Class
2 wiring compartment in the housing through star bushings or conduit and are connected to
screw terminals.
