Molded-Case Circuit Breakers, Fuses, Magnetic Contactors - Mitsubishi Electric MELSERVO-J4 Series Instruction Manual

Molded-case circuit breakers, fuses, magnetic contactors

For main circuit power supply
CAUTION
• To prevent the servo amplifier from smoke and a fire, select a molded-case circuit breaker which shuts off with high speed.
• 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.

*1 Use a molded-case circuit breaker which has the same or higher operation characteristics than our lineup.
*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.
