The Kinetix 350 drives use internal solid-state motor short-circuit protection and, when protected by suitable branch circuit protection, are rated for use on a circuit capable of delivering up to 100,000 A (fuses) and 65,000 A (circuit breakers).

Do not use circuit protection devices on the output of an AC drive as an isolating disconnect switch or motor overload device. These devices are designed to operate on sine wave voltage and the drive's PWM waveform does not allow it to operate properly. As a result,damage to the device occurs.

Make sure that the selected components are properly coordinated and meet acceptable codes including any requirements for branch circuit protection.

Evaluation of the short-circuit available current is critical and must be kept below the short-circuit current rating of the circuit breaker.
