Kinetix 5700 Regenerative Bus Supply
Connect the Braided Ground Strap
Circuit Breaker/Fuse Specifications
The Kinetix 5700 regenerative bus supplies use internal solid-state motor short-circuit
protection and, when protected by suitable branch circuit protection, are rated for use on a
circuit that can deliver up to 200,000 A (fuses) and 65,000 A (circuit breakers). 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 that the selected components are properly
coordinated and meet acceptable codes, which includes 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.
