Circuit Breaker and Fuse
Considerations
The Kinetix 6000 IAM module uses 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 200,000 A (fuses) and 65,000 A
(circuit breakers).
The Kinetix 5700 DC-bus power supplies also 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 200,000 A
(fuses) and 65,000 A (circuit breakers). 24V DC control power is sourced from
the customer-supplied 1606-XLxxx power supply.
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.
IMPORTANT While circuit breakers offer some convenience, there are limitations for their
use. Circuit breakers do not handle high current inrush as well as fuses.
