Operating and Function
b LT47, solid state overload relay, compares motor
current with preset load current threshold (LOAD).
b Motor currents are monitored through two internal
current transformers.
b CT hole size is 12 mm in diameter. Please don't
allow excessive force on CTs.
b D-Time counts down and is only available for motor starting.
During steady state, if motor current is greater than current
setting(overloaded), LT47 switches its contacts after O-Time.
b For shear-pin (mechanical shock) protection, set O-Time knob
to its minimum in order to trip in 0.2-0.3 s.
DANGER
HAZARD OF ELECTRIC SHOCK,
EXPLOSION, OR ARC FLASH
Disconnect all power before servicing
equipment.
Failure to follow these instructions
will result in death or serious injury.
PLEASE NOTE:
b Electrical equipment should be installed, operated,
serviced, and maintained only by qualied personnel.
b No responsibility is assumed by Schneider Electric

When motor current is less than minimum current setting
(< 0.5A), looping conductors through CT holes can
be used. The following table explains number of looping
for low current setting.
