5.3.2 MR-J4-series, no-fuse breakers, fuses, and magnetic contactors (recommended)
(1) For main circuit power supply
Always use one molded-case circuit breaker and one magnetic contactor with one converter unit. When
using a fuse instead of the molded-case circuit breaker, use the one having the specifications given in
this section.

Note 1. To 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.
