DB box mcb distribution board 12 way 3 phase breaker box distribution box
Product knowledge
For the distribution box with A power distribution transformer capacity of 100kV·A and above, consideration shall be given to the installation of temperature control relays (JU-3 or JU-4 ultra-small temperature relays) and axial flow fans on the side wall of the heat dissipation window in the box, which shall be installed on the left side of the box above the control electrical board. So that when the temperature in the box reaches a certain value (such as 40 ° C), the exhaust fan can be automatically started to force out the heat to make the box heat dissipation.
The protection circuit is adopted to prevent the failure of the external circuit supplied by the distribution box. Choose a small intelligent phase loss protector, such as DA88CM-II motor phase loss protection module (Shanghai product) installed in the distribution box to prevent the motor from burning out due to low-voltage phase loss operation.
