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.

(cid:2) Installation site should be in compliance with the following service conditions and installation methods, otherwise, it is difficult to guarantee
the performance of WKR5000 motor soft starter, the service life of soft starter would be reduced, the soft starter even would be damaged.
(cid:2) Mains voltage: AC 380V~1140V, 50/60HZ.
(cid:2) Applicable motor: squirrel cage three-phase asynchronous motor, rated power of motor should be matched with the rated power of soft
starter.
(cid:2) Starting frequency: not over 15 times per hour.
(cid:2) Cooling mode: natural air cooling K
(cid:2) Degree of protection: IP20(cid:2)
(cid:2) Ambient temperature: -30(cid:2)(cid:3)+55(cid:2)(cid:3)
(cid:2) Ambient humidity: relative humidity not exceed 95%, no condensation
(cid:2) Service place: draughty, free of corrosive gas or conductive dust, vibration should be lower than 0.5G.
(cid:2) Altitude: <3000m, if the altitude exceeds this height, please improve the power of soft starter correspondingly.

(cid:2) Water pump-makes use of water hammer phenomenon releasing pump during soft stop, saves system maintenance cost.
(cid:2) Ball mill-makes use of the ramp voltage start to reduce wear of gear torque and maintenance workload, it not only saves time, but also
saves cost.
(cid:2) Fan-reduces belt wear and mechanical shock, saves maintenance cost.
(cid:2) Compressor-makes use of rotation-clogging protection and quick protection functions, preventing from motor burn out due to overheating
caused by mechanical failure or block.
(cid:2) Transfer mechanism-realizes smooth starting through soft start, preventing product displacement or overflowing of liquid.
