4.3 Selection of Molded-Case Circuit Breaker, Fuse, and Magnetic Contactor (Example)

4.3.1 MR-J3 series, molded-case circuit breakers, fuses, and magnetic contactors

CAUTION
When using a fuse instead of the molded-case circuit breaker, use the one having the specifications given in
this section.

Note 1. When not using the servo amplifier as a UL/CSA Standard compliant product, K5 class fuse can be used.
2. Be sure to use a magnetic contactor with an operation delay time of 80ms or less.
3. Use a molded-case circuit breaker which has the same or more operation characteristics than our lineup.
Select a molded-case circuit breaker with a short shut-off time to prevent smoking
and fire from the servo amplifier.
Always use one molded-case circuit breaker and one magnetic contactor with one
servo amplifier.
