11.6 Molded-case circuit breakers, fuses, magnetic contactors
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. When having the servo amplifier comply with the IEC/EN/UL/CSA standard, refer to app. 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.
4. Use a molded-case circuit breaker having the operation characteristics equal to or higher than Mitsubishi Electric general-
purpose products.
The Type E Combination motor controller can also be used instead of a molded-case circuit breaker.
