Note:
(1) The circuit breaker and power cable specifications are selected based on the maximum power
(maximum current) of the units.
(2) The power cable specifications are obtained under the conditions that the ambient temperature is
40℃, the working temperature of multi-core copper cable (for example, YJV cable) is 90℃, and the
cable is exposed in cable troughs. In different applications, adjust the specifications based on national
standards.
(3) Only copper conductor cable can be used.
(4) The sectional area of a wire is applicable for a distance range of up to 15 m. If the distance is greater
than 15 m, increase the sectional area of the wire correspondingly to prevent the wire from being burned
due to overload current and to avoid fire.
(5) The circuit breaker specifications are obtained under the conditions that the ambient temperature is
40℃ when the circuit breaker is working. In different applications, adjust the specifications based on the
circuit breaker manual.
(6) The circuit breaker must support magnetic release and thermal release at the same time to protect
the system from short circuit and overload.
