contactors
Precautions
• Select the molded-case circuit breakers specified in this section.
• Wire the molded-case circuit breaker and magnetic contactor as recommended.
For main circuit power supply [G] [A]
When using a fuse instead of the molded-case circuit breaker, use the one having the specifications given in this section.

*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.
The motor circuit breaker (Type E combination motor controller) can also be used instead of a molded-case circuit breaker.
