PLEASE NOTE:

b Electrical equipment should be installed, operated,

serviced, and maintained only by qualified personnel.

for any consequences arising out of the use of this

material.

Operating and Function

b LR97D, solid state overload relay, compares motor

current with preset load current threshold (LOAD).

b Three phase motor currents are monitored through

three internal current transformers.

b D-Time counts down and is only available for

motor starting.

During steady state, if motor current is greater than the current setting (overloaded), LR97D

switches its contacts after O-Time.

In case of phase failure and locked rotor, trip delay time is 3 s and 0.5 s respectively.

b For shear-pin (mechanical shock) protection, set O-Time knob to its minimum in order to trip in 0.2-0.3 s.
