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): 300% five seconds min. and inrush current of 20 ms.
* 3. Make sure the current capacity is accurate. For the SERVOPACK with the cooling fan built-in, an
inrush current flows; 200% of the current capacity in the table above for two seconds, when turning ON
the control circuit power supply to start the fan working.
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 SGDM 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.
