Hammond Manufacturing 1435B NEMA12 P-BTN ENC 5.7X3.2 - 5.75 x 3.25 x 2.75

The 1435B carries a Type 12 and Type 13 rating with an IP54 seal, so it is built for dust, falling dirt, dripping non-corrosive liquids, and oil or coolant spray on a plant floor. It is not a wet-location or hosedown enclosure, so an outdoor or direct-spray position calls for a Type 4 or 4X box instead.

The box measures 5.75 by 3.25 by 2.75 inches. With a 3.25 inch face width and 5.75 inches of run, it is sized for a short vertical stack of standard 22mm or 30mm operators rather than a multi-column control station. The 2.75 inch depth is what governs whether your contact blocks and lamp modules clear the back wall, so count the stack depth of the operator plus blocks before committing.

It is listed to CSA, UL, and CE. The UL file is E65324 and the CSA certificate is LR21001, which are the numbers a plant electrical inspector or an AHJ will want referenced on the submittal.

Mild steel construction. That gives you a groundable metal enclosure that takes conduit hubs and machine-screw mounting well, but bare steel in a chemically aggressive or salt-air location will do better as a fiberglass or stainless box. For a normal indoor machine shop or packaging line, steel is the usual choice.

Made in Canada and USMCA compliant. That matters on public-sector and utility work where country of origin and trade-agreement status have to be documented on the submittal package.

Both. The 1435B is declared RoHS compliant and REACH compliant, which covers most institutional and OEM procurement specs that screen on restricted substances.

2.13 lbs empty. Light enough to hang off a machine guard, strut channel, or column bracket with standard hardware, though the loaded weight climbs once operators and contact blocks go in.

Order it as Hammond Manufacturing 1435B. That is the manufacturer part number for the Type 12/13 mild steel pushbutton enclosure measuring 5.75 x 3.25 x 2.75 inches.
