6. These wire sizes assume that the UL-compliant wires are used at the wiring length of 10m.
7. This model is for a single wire. The color must be specified separately.
11.6 Molded-case circuit 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.

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 (MC) with an operation delay time of 80ms or less. The operation delay time is the time
interval between current being applied to the coil until closure of contacts.
