Plan and Install the Kinetix 5100 Drive System Chapter 2
Circuit Breaker/Fuse Selection
The Kinetix 5100 drives use internal solid-state motor short-circuit protection
and, when connected to a suitable branch circuit protection, are rated for use on a
circuit that can deliver up to 5000 A (fuses or circuit breakers).
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.
See the Kinetix Servo Drives Specifications Technical Data, publication
KNX-TD003
, for input current and inrush current specifications for your
Kinetix 5100 drive.
Circuit Breaker/Fuse Specifications
Kinetix 5100 servo 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 5000 A when protected by fuses or circuit
breakers. These fuses and Allen-Bradley circuit breakers are recommended for use
with 2198-Exxxx-ERS drives.
Table 5 - Control Power Circuit-protection Specifications
IMPORTANT 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.
