Medium Size Screw Cover Electrical Enclosures & Junction Boxes
Medium screw cover enclosures from Boxco & Sealcon are industrial‑grade junction boxes designed for the secure housing of components, wiring, sensors or controls, sized for moderate scale installations. These enclosures feature a screw‑fastened removable cover which ensures reliable mechanical closure and access for maintenance in demanding environments.
Key technical considerations
-
Size range & footprint: Medium enclosures (210 x 230 mm up to approximately 400 x 400 mm) deliver enough internal volume for wiring bundles or modular electronics while still fitting panel or wall‑mounted applications.
-
Cover system & accessibility: The flat, screw‑on cover offers strong mechanical security and sealing repeatability. Some designs include screw plugs so cover screws remain captive.
-
Materials & construction: Common body materials include ABS plastic or polycarbonate for more rugged or corrosive settings. They provide enhanced durability and weather/chemical resistance.
-
Ingress protection & standards: Selection should match both mechanical and environmental requirements. Both Sealcon and Boxco can meet NEMA Type 4X for outdoor or harsh applications
-
Typical applications: These enclosures are suited for control‑panel instrumentation, intermediate junction boxes, HVAC terminal modules, lighting control hubs, small drive or PLC assemblies, or anywhere a mid‑sized housing delivers both capacity and manageability.
