The CN4SB73SS is a 70/70 A CU/AL, 3-wire splitter box from the CN4SBSS series of Type 4X stainless steel splitter boxes. It is the smallest stainless size, suited to electricians working in corrosive, washdown or outdoor locations where a painted steel box is not enough. The series is designed for distribution of up to 600 A (max) service at 600 V max using 3 or 4 wires, with 75° C conductor ampacity permitted.
The enclosure measures 12 x 10 x 5 in (305 x 254 x 127 mm) H x W x D, with a 5.85 in overall depth on the drawing. The drawing shows an 11.97 x 9.97 in door, a 10.52 x 8.39 in door opening, a 10.17 x 8.17 in inner panel, and Ø0.50 in wall mounting holes on 10.50 x 8.50 in centres.
It is formed from 16 gauge Type 304 stainless steel with smooth, continuously welded seams ground smooth, and the cover and enclosure are natural stainless steel with a smooth brushed finish. A formed lip and seamless poured-in place gasket exclude flowing liquids and contaminants. Splitter blocks are factory installed (reference CSBL125B). The door hangs on 304 stainless steel hinges with stainless steel pins, closes with quarter turn slot latches that require a tool, and is removable and interchangeable. A white powder coated inner panel is included on collar studs.
The CN4SB73SS is CSA Type 3R, 12, 4X and complies with IEC 60529, IP66. It includes a hardware kit with panel mounting nuts and sealing washers, accepts optional grounding kit CGK125, and has a 12 lbs (5.44 kg) shipping weight. REACH and RoHS compliant.
