A20H16ALP3PT

Overview

The Hoffman Enclosures A20H16ALP3PT is a wall-mount enclosure constructed from mild steel with a gray powder-coated finish. It measures 20 inches in length, 16 inches in width, and 6 inches in depth (508mm x 406.4mm x 152.4mm). The unit features a continuous hinge design and a single door equipped with a padlocking PowerGlide handle and a three-point latching mechanism. It provides NEMA Type 4 protection against environmental ingress.

Feature Summary

• Continuous hinge design for durable door operation
• Three-point latching system with padlocking capability
• Seamless foam-in-place gasket for environmental sealing

Applications

• Industrial control panel housing
• Outdoor electrical equipment protection
• Harsh environment instrumentation mounting

Procurement Notes

Verify the specific dimensional requirements against the 20x16x6 inch specification before ordering. Confirm that the NEMA Type 4 rating aligns with the intended environmental exposure conditions. Ensure the mounting surface supports the weight of the steel enclosure and its contents. Check for any required accessories such as DIN rails or knockouts not included in the standard configuration.

Selection Notes

Select this model when a robust, weather-resistant enclosure is required for indoor or outdoor use. The continuous hinge offers superior durability compared to standard hinges. The three-point latch ensures a tighter seal than two-point systems. Consider the internal volume of 1920 cubic inches for component placement planning.

Part Context

This part belongs to the nVent Hoffman A4W series of wall-mount enclosures. These units are designed for general industrial applications requiring protection against windblown dust, rain, sleet, snow, and hose-directed water. The series utilizes standardized dimensions to facilitate compatibility with common mounting hardware and internal components.

Replacement Considerations

Direct replacements must match the 20x16x6 inch footprint and NEMA Type 4 rating. Verify that substitute models include a continuous hinge and three-point latching mechanism to maintain equivalent security and sealing performance. Ensure material composition and finish compatibility with existing installation environments.
