Application fit

The enclosure provides a 12 in by 10 in by 4 in carbon steel housing rated NEMA 1 and IP30 for indoor electrical terminations. It serves electricians and panel builders who need a wall-mountable box with a solid screw-on cover and captive hardware. The galvanized gray finish resists corrosion in dry commercial environments.

Build integration

Pre-punched mounting holes allow direct attachment to walls or framing without additional brackets. The screw-latch closure secures the cover while captive screws reduce the risk of lost hardware during maintenance. The 12/14/16 gauge steel construction accepts standard knockouts and conduit fittings for cable entry.

Thermal and power profile

As a passive metal enclosure it adds no fan noise or active power draw to an installation. The galvanized steel body dissipates heat from internal components through natural convection across its surface area. Internal temperatures track ambient conditions in the conditioned spaces where NEMA 1 enclosures are specified.
