FAQs
To install the CV3110, verify three-pole mounting and ensure correct orientation for line and load terminals. Connect the three incoming phase conductors to the line terminals and the protected circuits to the load terminals. Confirm the unit is rated for 240 V and 100 A with a 65 kAIC interrupt capability. Tighten all connections to the manufacturer’s torque recommendations and secure the breaker within a compatible CH panel frame. This approach minimizes nuisance trips and ensures reliable coordination with downstream devices.
65 kAIC indicates the maximum fault current the breaker can interrupt without electrical or mechanical damage. It is essential for systems with high fault currents, such as large motors or feeders connected to robust power supplies. In facilities where fault currents may approach or exceed standard levels, selecting a 65 kAIC-rated CH breaker like the CV3110 helps ensure safe isolation, equipment protection, and compliance with design standards.
Yes. The CV3110 is a three‑pole molded case circuit breaker designed for motor feeders and other inductive loads in industrial settings. Its thermal magnetic operation provides overload protection and short‑circuit interruption, helping to prevent motor burnout and equipment damage. For motor start‑ups with high inrush, the CH series offers coordination options and appropriate interrupt ratings to balance protection with reliability.
Certification details for CV3110 vary by region. The data indicates “Certifications: Contact Manufacturer,” so verify regional approvals directly with Eaton for your locale. In practice, CH series breakers commonly align with global standards and local electrical codes; check the Eaton specification sheet and regional certificates to ensure compliance for your installation and maintenance program.
CH series breakers, including CV3110, are designed for long service life with minimal maintenance when installed correctly and operated within rated conditions. Regular inspections of mounting integrity, terminals, and enclosure cleanliness help prevent overheating and contact wear. By avoiding nuisance trips and extending replacement intervals, you reduce unplanned downtime and maintenance costs, improving total cost of ownership for panel protection and system reliability.
