How should a typical 2-pin KLIXON overload protection device be wired with the motor's common terminal?

A typical 2-pin KLIXON overload protection device is designed to interrupt the power circuit in series with the motor. Wiring it in series ensures that the current flowing to the motor must pass through the overload device. This is essential for its function, as the KLIXON device monitors the current and temperature of the motor. If the motor draws excessive current, indicating a potential overload condition, the KLIXON device will open the circuit and disconnect the power, protecting the motor from damage.

This series connection is fundamental to the operation of overload protection; it guarantees that any fault condition will trigger a response that effectively stops the motor from operating, preventing further issues such as overheating or burnout. Thus, wiring the KLIXON device in series with the motor's common terminal aligns with proper safety protocols in electrical design, ensuring the motor is safeguarded during overload situations.
