A48HS3712LP

Overview

The Hoffman Enclosures Inc. A48HS3712LP is a Type 4 disconnect enclosure constructed from steel with a polyester powder-coated gray finish. It measures 48 inches in length, 37.38 inches in width, and 12 inches in depth. The unit features a continuous hinge door secured by clamps on three sides to ensure environmental sealing. It provides NEMA 4/IP66 protection ratings and includes brackets welded directly to the structure for mounting circuit breakers or disconnect switches.

Feature Summary

• Clamp-secured door design on three sides for enhanced liquid and contaminant exclusion
• Welded internal brackets designed for direct circuit breaker or disconnect switch mounting
• Continuous hinge mechanism integrated into the enclosure structure

Applications

• Disconnect applications requiring clamp-secured doors
• Mounting of circuit breakers or disconnect switches
• Environments demanding NEMA 4 and IP66 protection ratings

Procurement Notes

Verify that the specific installation requires a clamp-latch door configuration rather than standard latches. Confirm that the welded bracket placement aligns with the intended switch or breaker model. Ensure the 48-inch length fits the designated panel space. Check if the 14-gauge steel thickness meets structural requirements for the mounted equipment weight.

Selection Notes

Select this model when high ingress protection is required alongside secure door fastening. The welded brackets simplify installation by eliminating separate mounting hardware for switches. Consider the large footprint and hard-to-handle classification during logistics planning. Verify compatibility with existing conduit entries and internal component layouts before finalizing the selection.
