MCCB or Fuse According to Power Capacity
The following table shows the MCCB or fuse capacity for each power supply
capacity.
*1
This is the net value at the rated load. When actually selecting fuses, determine the capacity with enough
margin for peak power operation.
*2
Operating characteristics (at 25°C): 2 seconds or more for 200%, 0.01 second or more for 700%
Notes: 1. A fast-operating fuse cannot be used because the servo amplifier power supply is a capacitor
input type. A fast-operating fuse may blow when the power is turned ON.
2. SGDH servo amplifiers do not have built-in ground protection circuits. To configure a safer
system, install a ground fault interrupter with or without a circuit breaker for protection against
overload and short circuit conditions.
