11.6 Molded-case circuit breakers, fuses, magnetic contactors (recommended)
Always use one molded-case circuit breaker and one magnetic contactor with one servo amplifier. When
using a fuse instead of the molded-case circuit breaker, use the one having the specifications given in this
section.

Note 1. When having the servo amplifier comply with the UL/CSA standard, refer to appendix 2.
2. Use a magnetic contactor with an operation delay time (interval between current being applied to
the coil until closure of contacts) of 80 ms or less.
3. S-N18 can be used when auxiliary contact is not required.
11.7 Power factor improving AC reactor
The following shows the advantages of using power factor improving AC reactor.
It improves the power factor by increasing the form factor of the servo amplifier's input current.
It decreases the power supply capacity.
The input power factor is improved to about 80%.
When using power factor improving reactors for two servo amplifiers or more, be sure to connect a power
factor improving reactor to each servo amplifier. If using only one power factor improving reactor, enough
improvement effect of phase factor cannot be obtained unless all servo amplifiers are operated.
