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 350 drives.

(1) Bulletin 1492 circuit protection devices have lower short-circuit current ratings than Bulletin 140M devices. Refer to http://ab.rockwellautomation.com/allenbradley/
productdirectory.page? for product literature with specific short-circuit ratings.
(2) For UL applications, Bulletin 140M devices are applied as self-protected combination motor controllers.
