11.10 Molded-case circuit breakers, fuses, magnetic contactors
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.
POINT
For the selection when the MR-J4-_B-RJ servo amplifier is used with the DC
power supply input, refer to app. 15.4.

(2) For control circuit power supply
When the wiring for the control circuit power supply (L11/L21) is thinner than that for the main circuit
power supply (L1/L2/L3), install an overcurrent protection device (molded-case circuit breaker or fuse) to
protect the branch circuit.
