JP Reactive Power Metering Comprehensive Distribution Cabinet

Application

ZM-JP comprehensive distribution panel is suitable for urban and suburban electric network, AC 50Hz, rated voltage 400V, rated current 600A and below as to distribute energy, control, compensate and protect for motor, illuminating, and distribution equipment and etc. This panel is developed from the network innovation for safe, economic, reasonable, secure operation, it is the comprehensive panel integrated with power distribution and reactive power ompensation. The panel has such advantages as high breaking capacity, good thermal stability, agile layout, practice, new structure, high protective degree (IP33), it is the new products in replace of old generation.

ZM-JP panel meet with standard of JB/DQ6141-86 Low voltage reactive power compensation device

Structure

The panel made of cold rolled steel plate with enough strength and rigidity, and can withstand the force come from short circuit.

Power source directly enter into metering compartment and separated from other parts, if closing rear door of the metering compartment, there.

can be Pb sealed to avoid electric theft.

In consideration of temperature rise, the panel upside has ventilating hole, and downside has shutter, these will form air convection to cooling.

The surface is epoxy dust painted, up to Ip33.

This panel is designed for outdoor use as well, rain proof.
