Milbank CT3R Hinge Cover Type 3R Steel No Knockouts ANSI 61 Gray

Yes. The CT3R is a Type 3R rated enclosure, which is the rating for outdoor use against rain, sleet and falling dirt. The body is G90 galvanized steel with a powder coat finish in ANSI 61 gray, and it is UL Listed. Type 3R is not rated for washdown or hosedown; if the location sees direct pressure spray, a 4 or 4X enclosure is the right call instead.

No. The CT3R is supplied with no knockouts, so every conduit entry is field-drilled or punched where you need it. That is the point of the blank design on a CT cabinet, where hub and conduit locations are dictated by the utility and the gear layout rather than by the factory. Plan on a hole saw or knockout punch set and appropriate raintight hubs or fittings for a Type 3R outdoor install, since a plain locknut connector will compromise the rating.

It is a current transformer cabinet, the box the utility's CTs and metering conductors land in ahead of the meter on larger commercial services. The hinge cover version swings open rather than lifting off, which matters on the bigger sizes like the 48x48 and 60x60 where a screw cover is a two-person job on a wall. Utilities typically seal the cover, so confirm your serving utility accepts a Milbank CT cabinet in the size you are ordering before the service is set.

Depth is driven by conductor size and bending space. The 36x30 and 36x36 bodies are offered at 10 inch depth for smaller services, and the same footprints come at 16 inches when you are pulling large parallel sets and need the bending room behind the CT bars. Middle ground is the 12 inch, offered on the 36x36 and 48x48, and the 60x60 comes at 13 inches. Size the depth to the wire bending space your conductors require, not just to the gear that has to fit inside.

That is Milbank 483616-CT3R. The numbering runs straight off the dimensions, so a 36x36x12 is 363612-CT3R and the largest, a 60x60x13, is 606013-CT3R. All are the hinge cover Type 3R blank enclosure in ANSI 61 gray with no knockouts.
