Eaton Specification Sheet - CVS3150X
The CVS3150X provides a 150 A amperage rating and a 42 kAIC interrupt capacity, enabling quick isolation of faulted loads and minimizing damage to feeders and downstream equipment. This combination improves electrical reliability and reduces unplanned downtime in data centers, manufacturing lines, and distribution panels. In practice, engineers can specify a single protective device for both main and feeder protection within CV-series panels, streamlining procurement and installation. With a three-pole CV frame, the CVS3150X supports full three-phase protection in compact footprints and accepts large conductor runs up to #4/0 kcmil. This enables straightforward wiring for feeders and branch circuits while maintaining tight panel densities. The device is compatible with common Cu/Al conductor sizes (#6-4/0 AWG) and standard termination practices, simplifying field assembly and reducing install time. Measured at 7.5 in in-depth and a 5x5 in footprint, the CVS3150X fits neatly into crowded electrical panels without sacrificing protection. Weighing about 4.4 lb, it offers manageable heft for mounting and maintenance during commissioning or retrofits. This compact size supports higher panel density and can simplify field drawings and BOMs. Certified to CSA Std. C22.2 No. 5 and UL 489, this device meets stringent safety and performance standards while the limited lifetime warranty reduces total cost of ownership. The combination of recognized certification plus long-term warranty translates into lower risk for audits and ongoing maintenance planning. Terminations support up to #4/0 kcmil maximum load and #6-4/0 Cu/Al wiring, enabling high-current distributions with robust connections. This aids in minimizing contact resistance and voltage drop in critical feeders, especially in factory automation and industrial control panels where reliability matters. Designed specifically for the CV molded-case family, the CVS3150X offers straightforward interchangeability within Eaton's low-voltage distribution ecosystem, reducing design risk and enabling quick replacements during maintenance windows.
