Core Product Features
The JP series low voltage integrated distribution box (also known as metering distribution box / power distribution box) is a low voltage terminal power distribution equipment independently developed and produced by our company, which integrates electric energy metering, power distribution control, overload protection and short circuit protection. The product fully complies with international IEC standards, domestic GB industry standards and power industry DL/T standards, and is one of the most widely used low voltage distribution terminal equipment in urban and rural power grids, industrial and mining enterprises, and civil buildings. Its core performance advantages are as follows:
Application Scenarios
This product is widely used in low voltage power distribution systems of urban and rural power grid transformation, rural power distribution areas, industrial and mining enterprises, industrial parks, civil buildings, commercial complexes, hospitals, schools, municipal engineering, data centers and other places. It is suitable for electric energy metering, power distribution, motor control, lighting distribution and reactive power compensation in 50/60Hz, 220V/380V low voltage power grids, and is the core equipment of low voltage power distribution terminals.
Complete climate control, automated feeding/egg collection, and manure drying systems. (Exported to 30+ countries)
Water treatment plants must operate reliably around the clock, often in remote locations. Unplanned downtime, high energy consumption, and inefficient manual processes are common pain points.
Mining operations demand rugged, reliable electrical equipment capable of performing in harsh conditions—extreme temperatures, dust, moisture, and vibration.
Food processing facilities require strict hygiene standards, precise temperature control, and reliable production line uptime.
Non-ferrous metal processing—including aluminum, copper, and rare earth refining—involves high-temperature operations, large electrical loads, and complex process control.
Residential and commercial communities need reliable, safe, and efficient power distribution.
