FAQs
CVS2175Y uses the CV frame and two-pole configuration, designed for Eaton CV-series panelboards. It accepts #6-4/0 AWG Cu/Al conductors and has a maximum line terminal rating of #4/0 kcmil. This makes it suitable for tenant mains in most standard low-voltage distribution panels, while maintaining straightforward field wiring and torque specifications for reliable long-term performance.
The CVS2175Y has a 42 kAIC interrupt rating, meaning it can safely interrupt fault currents up to 42,000 amperes without damage to the breaker or surrounding components. This provides strong protection for distribution feeders in commercial and light-industrial applications, reducing the risk of equipment damage and enabling safer shutdown during short-circuit events.
Yes. The CVS2175Y is a two-pole, 175 A molded case circuit breaker built on the CV frame, designed for tenant main protection in panelboards and load centers. Its high interrupt rating plus standard UL 489 and CSA certifications supports compliant, reliable protection for distributed circuits while fitting into common panel footprints.
CVS2175Y carries UL 489 and CSA Std. C22.2 No. 5 certifications. These indicate compliance with recognized safety and performance standards for low-voltage circuit breakers, aiding regulatory approvals and procurement qualifications. They are especially important in regulated environments such as data centers, healthcare, and manufacturing facilities where standard-compliant components are required.
The CVS2175Y carries a limited lifetime warranty, providing long-term protection relative to typical field replacements. Maintenance considerations are minimal, but periodic inspection of terminations and torque on connectors is recommended in high-vibration or harsh environments. For critical applications, incorporate routine preventive checks into your site’s maintenance strategy to sustain reliable protection.
