YASKAWA SGDS Sigma III Series - Molded-Case Circuit Breaker and Fuse Capacity

2.5 Selecting Peripheral Devices

2.5.2 Molded-case Circuit Breaker and Fuse Capacity
* 1. Nominal value at the rated load. The specified derating is required to select an appropriate
fuse capacity.
* 2. Cutoff characteristics (25°C): 200% two seconds min. and 700% 0.01 seconds min.
Note: Do not use a fast-acting fuse. Because the SERVOPACK’s power supply is a capacitor
input type, a fast-acting fuse may blow when the power is turned ON.
The SGDS SERVOPACK does not include a protective grounding circuit. Install a ground-fault protector to
protect the system against overload and short-circuit or protective grounding combined with the molded-
case circuit breaker.
