Note 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.
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.
