3.3 Molded-Case Circuit Breakers and Fuses
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.
