Molded-case circuit breakers, fuses, magnetic
contactors
When using a fuse instead of the molded-case circuit breaker, use the one having the specifications given in this section.
Precautions
• Select the molded-case circuit breakers specified in this section.
• Wire the molded-case circuit breaker and magnetic contactor as recommended.

*1 Use a fuse to make the servo amplifier comply with UL/CSA standards. To make the servo amplifier comply with IEC/EN/UL/CSA
standards, refer to "MR-JET Safety Instructions and Precautions for AC Servos (IB(NA)-0300492)" for selection of molded-case circuit
breakers and fuses.
*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 Use a molded-case circuit breaker that has operation characteristics equal to or higher than Mitsubishi Electric general-purpose
products.
A motor circuit breaker (Type E Combination motor controller) can also be used instead of a molded-case circuit breaker.
Use the motor circuit breaker (Type E Combination motor controller) with the line side terminal adapter UT-CV3 and the short-
circuit indicator unit UT-TU.
