Product Specifications

Technical details and manufacturing context for Panel Enclosure

Definition
A panel enclosure is a protective housing designed to contain and safeguard the electrical components, meters, and instrumentation within a metering panel. Its primary function is to provide physical protection, environmental sealing, and operator safety. The enclosure is constructed from materials such as galvanized steel, stainless steel, or polycarbonate, offering durability and resistance to corrosion. It features a rigid, sealed structure that isolates internal components from external factors like dust, moisture, and impact, while preventing accidental contact with live parts. This ensures safe operation and extends the lifespan of the metering equipment. The enclosure is available in a standard size of 300x400x150 mm (W x H x D), with custom sizes available upon request. The material is cold-rolled steel (SPCC) with a thickness of 1.5 mm, conforming to GB/T 11253. The surface is treated with a textured powder coating in RAL 7035. It provides an IP54 rating, offering dust protection and resistance to water splashing, and an IK08 degree of protection, withstanding 5 J impact energy. The operating temperature range is -25 to 55 °C for continuous operation. The rated voltage is up to 400 V AC, and the rated current is up to 100 A, both in accordance with IEC 61439. The enclosure weighs approximately 8.5 kg without components. It is designed for wall mounting with mounting brackets, and the door opens to an angle of 110 degrees with a stay. Cable entry is provided via 20 M20 knockouts on the top and bottom. For any specific application, it is essential to verify model-specific values and standards with the legal manufacturer or supplier.
Working Principle
The enclosure operates by providing a rigid, sealed structure that isolates internal electrical components from external environmental factors such as dust, moisture, and impact. This isolation prevents contamination and physical damage, ensuring reliable operation. Additionally, the enclosure prevents accidental contact with live parts, enhancing operator safety. The IP54 rating ensures protection against dust ingress and water splashing, while the IK08 rating indicates resistance to mechanical impacts. The enclosure's design facilitates proper heat dissipation and cable management, contributing to the longevity and safe operation of the metering equipment.
