Using an AC Power Supply
Use a molded-case circuit breaker and fuse to protect the power supply line. They protect the
power line by shutting OFF the circuit when overcurrent is detected. Select these devices
based on the information in the following tables.
Note: The following tables provide the net values of the current capacity and inrush current. Select a fuse and a
molded-case circuit breaker that meet the following conditions.
• Main circuit and control circuit: No breaking at three times the current value given in the table for 5 s.
• Inrush current: No breaking at the current value given in the table for 20 ms.
