Part 9: Review on Replacement of Optional Peripheral Equipment
9 - 21
4.3.2 MR-J4 series, molded-case circuit breakers, fuses, and magnetic contactors (recommended)
(1) For main circuit power supply
CAUTION
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.
When using a fuse instead of the molded-case circuit breaker, use the one having the specifications given in
this section.

Note 1. In order for the servo amplifier to comply with the UL/CSA standard, refer to the applicable "Servo Amplifier Instruction
Manual".
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.
