WKR5000 motor soft starter is applicable for three-phase AC squirrel cage asynchronous motors of 5.5kW~600kW and AC 380V~1140V, 50
(60)Hz, rated current 1200A and below, the panel operation display mode not only is convenient for parameter setting and modifying as well
as understanding various functions of soft starter for users, but also is convenient for observing the working state of soft starter and motor; it
has perfect protection functions for motor starting and running without being equipped with thermal relay; its closed-loop control sharply
improves stationarity and reliability of soft torque start and soft torque stop of motor; it employs bypass contactor for running, the operating
power consumption is almost zero, this improves its reliability while reducing its volume.
The motor soft starter is of unit type, a circuit breaker (for short-circuit protection) and AC contactor (for bypass after finishing starting) are
required to be installed in the cabinet, and form into motor control circuit with the switch.
