Description

The wiring of electrical components is a typical task in the field of refrigeration. Besides the design and operation of the individual components, knowledge about the interaction of the components in circuits is an important learning objective. Safety aspects also play an important role. With this knowledge and these skills can be acquired.

The electrical components are arranged clearly visible. All components are connected on terminal blocks. Using the cables included in the scope of delivery it is possible to set up different circuits correctly and operationally. Lamps simulate the consumers. All components are operated and tested with mains voltage to provide high relevance for practice.
