Description

The wiring of electrical components for the start and operation of refrigerant compressors is a typical task in the field of refrigeration. Safety aspects also play an important role. With this knowledge and these skills can be acquired. All components are operated and tested with mains voltage to provide high relevance for practice. The electrical components for the start and operation of the refrigerant compressor are arranged clearly visible. The electrical connection of the individual components is made with cables via the lab jacks. The components are e.g. the capacitor and start-up relay necessary to start the motor. The circuit diagram on the front panel enables the easy allocation of the individual components.
