Compact design saves
on precious panel space.
High current contacts can
switch up to 480VA @
240 V A C.
Screw terminals eliminate
messy pigtail connections.
Requires no external
power because power
is induced from the
motor conductor.

Model LSR-0 is a preset load sensor designed to switch whenever
15A is present and drop out at 2.5A.The LSR-0 is used commonly
as lockout protection on oil pressure controls due to compressor
overload shutdown.It can also be used to inter lock fans, compressors,
and motors; to indicate equipment status such as feed rates, tool wear,
loss of prime on pumps, mixer viscosity, and all types of over and
under load conditions, or to stage pump motors, chillers, and other
machinery.
This device combines a current transformer (CT), transducer, and high
current output relay together to switch alarm circuits, contactors, or
most resistive or inductive loads.The LSR-0 can perform the function
of an auxiliary contact, yet has the advantages of universal application
and isolation.
