How is a coil on a current relay typically connected?

A coil on a current relay is typically connected in series with the run terminal. This configuration allows the relay to monitor the current flowing to the compressor motor. When the compressor is operating, the current flowing through the run terminal energizes the coil. If the current reaches a predetermined level, the relay activates, which can serve functions such as protecting the compressor from overload conditions or facilitating starting and stopping operations.

This method of connection is essential for the relay to function correctly in applications requiring motor protection and efficient operation. The inclusion of the coil in this position ensures accurate detection of running conditions and helps maintain the proper operation of refrigeration systems.
