Power Distribution Board, Vacuum Circuit Breaker
Introduction - Safe Power Distribution BoardJM4-2 Safe Power Distribution Board is designed and developed by our company which has protective functions against electric leakage, overload and short circuit. It is especially applied to terminal power distribution, lighting and power in such public places as schools, hospitals, shopping malls, business buildings and plants, etc.
Structure Features - Safe Power Distribution Board
1. Separate installment: achieve the standardization of non-standardization
2. Reasonable structure: large wiring space and capacity
3. Stable performance: connected by copper rib rows of heat-shrinkable tubes
4. Safe operation: the operator is isolated with the charged parts; protection rank is IP20
5. Easy to handle: the indoor adopts spring hinge, springboard button and unique conductive track.
JM4-2 Safe Power Distribution Board
1. The protection rank of its shell has reached as high as IP30, IP41. It allows separate installment of single and secondary circuit loops in the small cabinet and enables non-standard Power Distribution Board standardized. In some cases, the input wire can be introduced by the cable on the top of the cabinet or directly connected by the input terminal of the Busbar Bridge.
2. Installment of the parts: vertical, horizontal and rib type.
Terms of Use - JM4-2 Safe Power Distribution Board
1. Environment Temperature:
The maximum temperature is below +40°C and the minimum temperature is above -5°C. The average temperature in 24 hours is below +35°C.
2. Atmospheric Conditions:
Clean air. The relative temperature is below 50% when the air temperature is +40°C and lower temperature allows relatively high humidity. Eg: +20°C, the relative humidity is 90%.
3.Other Conditions:
Equipments are installed below the height of 2000 meters above sea level. The earthquake intensity cannot exceed 8 degree. No fire or explosion hazards. The insulated gas and conductive dust are not strong enough to damage or rust Power Distribution Board.
