Installing the Kinetix 300 Drive System
Circuit Breaker/Fuse Specifications
While circuit breakers offer some convenience, there are limitations for their use.
Circuit breakers do not handle high current inrush as well as fuses.
Make sure 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.
Use class CC or T fast-acting current-limiting type fuses, 200,000 AIC,
preferred. Use Bussmann KTK-R, JJN, JJS or equivalent. Thermal-magnetic type
breakers preferred. The following fuse examples and Allen-Bradley® circuit
breakers are recommended for use with Kinetix 300 drives.

(1) When using Bulletin 1492 circuit protection devices, the maximum short circuit current available from the source is limited to
5000 A.

(2) Use fully-rated short-circuit protection circuit breaker for device branch circuit protection only when there is an upstream fully-rated
breaker.
