APPENDIX
App. - 71
App. 15.4 Molded-case circuit breakers, fuses, magnetic contactors
(1) For main circuit power supply
CAUTION
To prevent the servo amplifier from smoke and a fire, select a molded-case circuit
breaker which shuts off with high speed.
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. Use a molded-case circuit breaker having the operation characteristics equal to or higher than Mitsubishi Electric general-
purpose products.
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.
