Hammond N1A42249 42x24x9" NEMA 1 Wallmount Enclosure with Panel

The Hammond N1A42249 is a UL 50 and CSA Type 1 mild steel wallmount enclosure measuring 42 in high x 24 in wide x 9 in deep (1,067 mm x 610 mm x 229 mm). It is designed for indoor use to house controls, instruments and components that do not require oil-tight or dust-tight protection, making it a practical choice for panel builders, OEM engineers and electricians. Its 9 in depth is the middle of the three N1A depths (7, 9 and 12 in).

The enclosure is formed and spot welded from steel and finished in ANSI 61 gray powder coating. A removable inner panel, 38.00 in (965 mm) high by 22.50 in (572 mm) wide and finished in white powder coating, mounts in the rear of the enclosure on collar studs. Because the door is taller than 36 in, it is mounted on a continuous hinge and is secured with two slotted quarter turn latches. A bonding stud is provided on the door and a grounding stud in the box.

The upright 42 x 24 in face gives a door opening of 22.75 in wide by 40.75 in high per the drawing, and the door itself measures 24.38 in x 42.38 in (W x H). Clear space available on the door is 22.75 in wide, with 18.25 in high areas shown on the drawing, useful when planning door-mounted devices.

Mounting holes are provided in the rear of the enclosure, laid out on 16.75 in x 39.88 in centres per the drawing; the optional N1AMFK mounting foot kit (set of 4 feet) provides a wall mounting alternative. N1A42249 complies with NEMA Type 1 and IEC 60529 IP20 (UL File E71072, CSA Cert. LR21001) and ships in a box at 111 lbs (50.35 kg).
