Feature: Thermal-magnetic protection delivers coordinated overload and short-circuit response for stable power distribution. Business Impact: This reduces nuisance trips and minimizes arc flash risk, translating to lower downtime and safer operations. Application: Ideal for 3-pole, 240 V panels in manufacturing lines and process controls where consistent protection is essential. Feature: 42 kAIC interrupt rating provides substantial fault-current capability for feeders and main distribution. Business Impact: Higher fault handling reduces upstream damages and simplifies coordination with upstream protective devices. Application: Suitable for industrial feeders and main breaker roles in equipment racks and control panels. Feature: 100 A at 240 V, 3-pole design aligns with standard three-phase electrical systems. Business Impact: Enables precise overload protection with balanced phase protection, improving reliability and compliance with design specs. Application: Fits common industrial power distribution architectures and existing CH-series installations. Feature: Line terminals and a compact footprint simplify wiring and mounting. Business Impact: Reduces panel space, shortens install time, and reduces wiring errors. Application: Quick retrofits in crowded switchgear and new panel builds where space is a premium. Feature: CH-series compatibility ensures seamless integration with Eaton protection schemes. Business Impact: Streamlines spare parts management and service continuity across multiple panels. Application: Ideal for upgrades within Eaton ecosystems or when replacing older CH devices. Feature: Molded housing provides durability and product longevity in industrial environments. Business Impact: Lower maintenance costs and predictable performance under vibration, temperature, and dust.

FAQs
CVS3110Y is a three-pole, 240 V device designed for line-terminal mounting. When installing, verify panel rating supports 100 A and 42 kAIC, align bus connections with the CVS type, and tighten terminations to the manufacturer’s torque specifications. Maintain proper clearance for heat dissipation and follow standard field wiring practices for molded case breakers within CH-series panels.
The CVS3110Y provides a 42 kAIC interrupt rating, enabling safe interruption of high fault currents and reducing upstream fault propagation. This makes it well-suited for industrial feeders, main distribution, and other installations where robust fault clearance is critical and upstream protection coordination is essential.
CVS3110Y offers general protection for three-phase power at 100 A and 240 V but is not a dedicated motor-protection device. For motor applications, pair it with motor protective devices and select coordination that accommodates motor inrush. It works well as a main or feeder breaker within CH-series panel setups that protect motor loads.
The spec sheet lists certifications as 'Contact Manufacturer,' so verify current UL, CSA, and CE approvals with Eaton or the latest datasheet. Always consult the Eaton Specification Sheet CVS3110Y and warranty documentation for up-to-date regulatory compliance and coverage before procurement.
The molded housing and solid build reduce maintenance frequency and failure risk, supporting higher equipment availability. As a compatible CH-series component, it simplifies spare parts management and procurement across asset-heavy facilities, contributing to lower lifecycle costs, predictable uptime, and easier upgrades during panel modernization.
