CURRENT SWITCH AND RELAY
RIBX SERIES
DESCRIPTION
The Relay in a Box RIBX Series provides a unique
and cost-effective solution to on/off motor control and
current sensing status indication. Combined in a single, convenient junction box with high and low voltage
separation are a control relay and a current sensing
status switch. A three-position closed/open/auto switch
is available to override the output of the relay. This versatile product allows both control and status sensing of
electrical loads by a BAS, all in a self-contained, easyto-install housing.

APPLICATION
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.
