B-Line 303611 HRTCT Eaton series CT hinged cover, 3R, 12 gauge steel, ANSI 61 gray paint finish Galvanized steel, Surface mount, 1P or 3P, Hinged cover

The 303611 HRTCT current transformer cabinet measures 30 in height, 36 in width, and 11 in depth. That 11 in depth matters most on the wall side: you need the clearance in front of the enclosure for the hinged cover to swing, and enough wall depth behind for surface mounting. The unit weighs 113.293 lb, so plan on two people and lag anchors into structure, not drywall alone.

Yes. It carries a 3R degree of protection, which is the rating for outdoor use against falling rain, sleet and external ice formation. It is not rated for hosedown or washdown areas, so for pressurized water or heavy industrial washing you want a 4 or 4X enclosure instead. The 12 gauge steel body with galvanized steel construction and ANSI 61 gray paint is what gets it through outdoor exposure.

Either. The 303611 HRTCT is listed for single phase or three phase applications, so the same enclosure serves a 1P residential or light commercial meter setup and a 3P commercial service. What differs is the CT and wiring arrangement you install inside; the cabinet itself does not change.

No. The 303611 HRTCT is the enclosure only: a 12 gauge steel, 3R rated, surface mount box with a hinged cover. The CTs, mounting brackets for them, conductors, lugs and any sealing hardware the utility requires are separate. Size the CTs to the service and the utility's metering spec.

UL certification is carried on the 303611 HRTCT CT cabinet. Utilities also have their own approved-equipment lists for metering enclosures, so check the local utility's CT cabinet spec for the required size and cover style before you set it.

Hinged cover. That is the practical difference from a screw-cover CT cabinet: an electrician or meter tech can open it one-handed without setting a 36 in wide panel on the ground, which matters on a 30 by 36 in box mounted at meter height. Utilities frequently require the cover be sealable, so confirm the sealing arrangement their spec calls for.

ANSI 61 gray is the standard light gray used across most switchboards, panelboards and industrial control enclosures, so the 303611 HRTCT will read as a match alongside typical electrical gear rather than standing out. The paint sits over galvanized steel, which gives you a second layer of corrosion protection if the topcoat gets scratched during install.
