Protection

Polarity: Damage will not occur for up to 10 minutes with positive and

negative leads connected in reverse.

Locked Rotor: Within 72 hours of a rotor locking condition, at the rated

voltage and operating temperature, the impedance of the motor winding

will protect the motor from damage.
