FAQs
The enclosure is designed to be bayed with modular expansion in mind. Begin by anchoring the base/plinth, ensuring gland plates align with planned cable routes. Attach additional bay units via the 25 mm punchings in the roof and base, then mount the front door (which can be swapped to the left) and run cables through the gland entries. Finally, verify the 4-point locking system BJ20027 engages correctly and seal the rain canopy to maintain IP55 protection.
Key protections include IP55 ingress protection, NEMA 3R enclosure protection, and IK10 impact resistance. The enclosure frame is stainless steel 1.4301 (AISI 304) with aluminium panels and base/plinth trim, all finished in UV-resistant powder coating. The rain canopy is aluminium, contributing to weather resistance and longevity in outdoor deployments.
Yes. The combination of weatherproofing (IP55), impact resistance (IK10), and robust materials makes it well suited for outdoor telecom cabinets, remote power distribution panels, and other control enclosures exposed to weather. Its modular baying capability also supports scalable deployments typical in telecom and utility configurations.
The enclosure offers IP55 protection and IK10 impact resistance, along with NEMA 3R protection, meeting common industrial outdoor standards. Its earthed, double-panel construction and use of corrosion-resistant materials help ensure safety and reliability in regulated environments, while the left-right door swapping adds installation flexibility for site-specific requirements.
The stainless steel frame and UV-resistant powder coating minimize corrosion and repaint needs, reducing lifecycle maintenance. Baying capability enables staged capacity expansion without full cabinet replacement, lowering capex and downtime. The integrated rain canopy and gland plates streamline cabling and weather sealing, delivering faster maintenance windows and a clearer path to return on investment.
