Final answer:
A pilot duty overload protector trips the circuit to stop the motor and prevent damage when it detects an overload.
When a pilot duty overload protecting a motor detects an overload, it trips a circuit breaker or disconnects the power supply to prevent damage to the motor.
Step-by-step explanation:
When a pilot duty overload protector protecting a motor detects an overload, it trips the circuit and stops the motor to prevent damage.
Overload protectors are designed to sense overheating or an excessive current draw, indicating that the motor is working harder than its designed capacity, which can cause damage over time.
The device protects motors from potential damage by interrupting the electrical supply, allowing the motor to cool down and preventing burnout or failure.
