(5) How to Select Molded-case Circuit Breaker and Fuse Capacities
The following table shows the SERVOPACK’s current capacities and inrush current.
Select a molded-case circuit breaker and fuses in accordance with these specifications.
Note 1. To comply with the EU low voltage directive, connect a fuse to the input side as protection against accidents
caused by short-circuits.
Select fuses or molded-case circuit breakers 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.
2. The following restrictions apply to UL standard compliance conditions.
