(6) How to Select Molded-case Circuit Breaker and Fuse Capacities
The following table shows the SERVOPACK’s current capacities and inrush current when using single-phase
200 V power supply. Select a molded-case circuit breaker and fuses in accordance with these specifications.
Note: To comply with the EU low voltage directive, connect a fuse to the input side as protection against accidents caused
by short-circuits. Select the fuse for the input side that are compliant with UL standards.
The table above also provides the net values of current capacity and inrush current. Select a fuse and a molded-case
circuit breaker which meet the breaking characteristics shown below.
• Main circuit, control circuit: No breaking at three times the current values shown in the table for 5 s.
• Inrush current: No breaking at the current values shown in the table for 20 ms.
