(5) Molded-case Circuit Breaker and Fuse Capacities
The following table describes the molded-case circuit breaker and fuse capacities of the SERVOPACK.
Note 1. To comply with the low voltage directive, connect a fuse to the input side. Select the fuse or molded-case circuit
breaker for the input side from among models 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 of the table for 5 s.
• Inrush current: No breaking at the same current values of the table for 20 ms.
2. In accordance with UL standards, the following restrictions apply.
