[79] What size circuit breaker should I use for this VFD?
Share
The 2.2kW spindle has a power rating of 2.2kW or 2200 watts. If the VFD AC voltage input is rated for 220 volts, then 2200 watts / 220 volts is 10 amps, so a 15 or 20 amp breaker will work. If the VFD AC voltage input is rated for 110 volts, then 2200 watts / 110 volts is 20 amps, so a 25 or 30 amp breaker will work. Additional Information: Additional Information:
