(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.
∗ The official model number is SGDV-120A01A008000.
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 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.
2. The following restrictions apply to UL standard compliance conditions for SGDV-120A01A008000 SERVO-
PACKs.
Current rating when using molded-case circuit breaker: 40 A max.
