Compact design saves
precious panel space.

Relay contacts can switch
up to 480 VA @ 240VAC,
5A continuous.Unique LED

indicator gives clear visual
status of relay state.

Fast-on terminals or optional
depluggable screw terminals
ensure quick, simple
connections.

Requires no external power,
power is induced from the
AC conductor.

The Model LSRX is an AC current sensor designed to energize the
output contact whenever 4.5 Amps or greater is present. The LSRX is used
commonly as an AC current proof relay to indicat e if a motor is operating. It
can also be used to interlock fans, c ompressors, and motors; to indicate
equipment status such as feed rates, tool wear, loss of prime on pumps,
mixer viscosity , and all types of current sensing conditions; or to stage
pump motors, chillers, or other machinery.

This device combines a current transformer (CT), transducer, and high
current output relay together to switch alarm circuits, contactors, and most
resistive or inductive loads. The LSRX can perform the function of an
auxiliary contact, yet has the advantages of universal application
and isolation.
