4.3.3 MR-J3W series, no-fuse breakers, fuses, magnetic contactors
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.
When using two different types of motors in combination from a rotary servo motor, a select a molded-case
circuit breaker, a fuse or a magnetic contactor temporarily assuming that the same type of the motors are
used for both axes. After selecting for the two types, use the larger molded-case circuit breaker, fuse or
magnetic contactor.

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.
