Application and purpose

The Hoffman A643DSC is a carbon-steel electrical enclosure rated for NEMA 4, 6, 12 and 13 environments. It suits installers who need a wall-mounted junction or terminal box that resists water, dust, oil and coolant in industrial settings.

Decisive specification

The enclosure carries an IP67 rating and meets CSA, cUL, IEC and UL standards, confirming suitability for submersion and high-pressure wash-down. Buyers who need a different NEMA rating or a non-metallic housing must select another model.

Thermals noise and power

The solid steel body with ANSI 61 polyester powder finish dissipates heat passively and contains no fans, so acoustic output is zero. A neoprene gasket and screw-on flanged cover maintain the seal without adding active cooling load.

Questions about this item

What do the NEMA 4, 6, 12, 13 ratings mean once this enclosure is installed?

The NEMA 4 and 6 ratings provide protection against water ingress from hose-directed streams and temporary submersion, while NEMA 12 and 13 protect against circulating dust, lint, and oil or coolant seepage indoors.

What does the IP67 rating cap in practice for this enclosure?

IP67 certifies the enclosure is dust-tight and can withstand immersion in water up to one metre deep for thirty minutes, limiting ingress to levels that will not harm internal components.

What physical mounting features does this 5.75 in H x 4.0 in W x 2.75 in D carbon steel box include?

The 16-gauge carbon steel body has external wall-mounting brackets and a flanged, formed cover secured with screws and a neoprene gasket for a tight seal.
