The Hoffman Enclosures Inc. A20H1606ALLP is a wall-mount electrical enclosure constructed from aluminum with a smooth brushed finish on the door front. It measures 20 inches in height, 16 inches in width, and 6 inches in depth (508 mm x 406 mm x 152 mm). The unit features a clamp cover design with continuous hinge functionality and includes stainless steel screws and clamps. It provides IP66 ingress protection and holds UL 508A, CUL, NEMA 3R, 4, and 4X ratings.
Verify that the specific order matches the A20H1606ALLP designation to ensure correct dimensions of 20x16x6 inches. Confirm the requirement for aluminum construction and stainless steel hardware. Ensure compatibility with existing mounting infrastructure for wall installation. Check for any specific certification requirements such as UL 508A or CUL depending on regional regulations. Validate that the clamp cover style meets operational access needs.
Select this model when an aluminum enclosure with NEMA 4X protection is required for wall mounting. The 20x16x6 inch size offers a balance between internal component capacity and external space constraints. The continuous hinge and clamp system facilitate easier access compared to traditional bolted doors. Consider the brushed aluminum finish for aesthetic integration in visible industrial environments. Ensure the IP66 rating aligns with the specific environmental exposure levels of the installation site.
This part belongs to the Hoffman A-series of electrical enclosures, designed for general industrial use. The A20H1606ALLP specifically denotes the height, width, and depth dimensions within the product line. It is manufactured by nVent Hoffman, a provider of electrical enclosure solutions. The series is known for offering various materials and protection ratings to suit different environmental challenges.
No direct public substitute part numbers are confirmed for this specific model. When replacing, verify exact dimensional compatibility and protection rating equivalence. Ensure the replacement material and hardware specifications match the original requirements.
