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.
