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°C, the working temperature of multi-core copper cable (for example, YJV cable)
is 90°C, and the cable is exposed in cable troughs. In different applications, adjust the
specifications based on national standards.
③ Only copper 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.
⑤The circuit breaker specifications are obtained under the conditions that the ambient
temperature is 40°C 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.
