Hammond C3RWT660 6x6x60 Inch Type 3R Galvanized Wiring Trough

The C3RWT660 is a five-foot Type 3R wiring trough in a 6 x 6 in section, intended to protect multiple wiring junctions outdoors across a longer row of meters, disconnects or panels.

Like every trough in the C3RWT series, it is formed and spot welded from galvanized steel (the series is made in 14 or 16 gauge), and both the enclosure and cover are finished in ANSI 61 gray powder coating, which is why the part is listed as Galv/Gray. A drip shield top design protects the enclosure against rain, snow or sleet, and the slip on front cover removes for access and is secured with screws.

The nominal size is 6 in x 6 in x 60 in (152 mm x 152 mm x 1,524 mm), with a shipping weight of 28 lbs (12.70 kg). The part drawing shows an overall length of 60.88 in and a 6.44 x 6.44 in overall section including the drip shield, a front opening of 58.75 x 4.42 in, and inside dimensions of 5.89 x 5.89 in. Mounting is through 4 embossed holes of 0.30 in diameter on the back of the enclosure, spaced 56.00 in lengthwise and 3.75 in vertically.

The C3RWT660 is listed under UL870 Type 3R (UL File # E186830) and CSA Type 3R (CSA Cert. # LL21312), and complies with NEMA Type 3R and IEC 60529, IP24. To meet UL870 - 2008 requirements the series specification sheet shows a bonding stud on the cover and a ground stud in the enclosure. The part is RoHS and REACH compliant. Note that effective August 17, 2026 the grounding strap and padlocking hasp previously included with each trough are no longer provided.
