C.4 Breaker and electromagnetic contactor
It is necessary to add fuse for the avoidance of overload.
It is appropriate to use a breaker (MCCB) which complies with the VFD power in the 3-phase
AC power and input power and terminals. The capacity of the VFD should be 1.5-2 times of
the rated current.
Due to the inherent operating principle and construction of circuit
breakers, independent of the manufacturer, hot ionized gases may
escape from the breaker enclosure in case of a short-circuit. To ensure
safe use, special attention must be paid to the installation and
placement of the breakers. Follow the manufacturer's instructions.
It is necessary to install the electromagnetic contactor in the input side to control the switching
on and off safety of the main circuit. It can switch off the input power supply when system
faults.
