Soft starter 22kW, 45A, integrated bypass PR5300 022G3
The soft starter PR5300 is used to smoothly start and stop three-phase asynchronous electric motors with a capacity of up to 400 kW.
The integrated bypass contactor helps save time when commissioning equipment.
The use of a soft starter with three-phase switching allows to reduce the starting currents of asynchronous motors, phase imbalance during start-up, provides a smooth stepless acceleration of the motor.
The use of soft starters makes it possible to achieve the following results:
- extending the life of the electric motor by reducing hard starting loads;
- reducing the load on the electrical network during the launch of powerful electric motors;
- increase in throughput of the power supply network;
- reduction of loads on the transformer of the power substation;
- the exception of a voltage drop in the network at the time of starting powerful motors.
Supported Soft Start Modes:
- start-up with limitation of inrush current;
- start-up with a constant increase in voltage;
- start with a jerk;
- start-up with a constant increase in current;
- start-up with double regulation (current and voltage).
Supported Stop Modes:
- smooth stop;
- stop by self-running.
Protection against:
- high and low voltage;
- loss and phase imbalance;
- excess inrush current;
- short circuit;
- automatic restart;
- idle move.
Management is available from the built-in remote control and external terminals.
Printed circuit boards are coated with acrylic varnish.
Operating temperature range - -10 ... + 40 ° C
