According to the working principle and structure of breakers, if the manufacturer's
regulation is not followed, hot ionized gases may escape from the breaker
enclosure when a short-circuit occurs. To ensure safe use, exercise extra caution
when installing and placing the breaker. Follow the manufacturer's instructions.
To ensure safety, you can configure an electromagnetic contactor on the input side to control the
switch-on and switch-off of the main circuit power, so that the input power supply of the VFD can be
effectively cut off when a system fault occurs.
