Eaton Specification Sheet - CVS3175X
Paragraph 1: The CVS3175X is a molded case circuit breaker with a 175 A rating and 42 kAIC interrupt capacity built on the CV frame, delivering robust protection for three‑phase power systems in compact footprints. The three-pole configuration supports balanced protection across phases, making it ideal for load centers and motor control centers in demanding industrial environments. Paragraph 2: Terminals and wiring compatibility are designed for straightforward field installation. The CVS3175X accepts #6-4/0 AWG Cu/Al conductors and #4/0 kcmil maximum load, enabling robust feeder connections without exotic accessories. This reduces termination errors and ensures consistent torque performance across installations. In practice, technicians experience faster wiring, easier verification, less risk during panel upgrades, and shorter commissioning timelines at handover. Paragraph 3: Space-efficient design helps maximize control room real estate. With a compact 7.5 in length, 5 in height, and 5 in width, plus a 4.4 lb weight, the CVS3175X simplifies mounting and reduces enclosure footprint. The three-pole configuration supports balanced three-phase protection, while the 42 kAIC interrupt capability provides reliable fault interruption for moderate to heavy duty systems, lowering the probability of cascading outages in critical lines. Its maintenance-friendly mounting scheme supports quick replacement and routine checks, further reducing facility downtime. Paragraph 4: Compliance and ongoing maintenance are supported by UL 489 and CSA certifications, ensuring the CVS3175X meets widely adopted electrical safety standards. For design and procurement, Eaton's specification sheet CVS3175X and product catalogs provide clear guidance on terminal sizes, torque, and mounting. The limited lifetime warranty further reduces lifecycle costs by lowering replacement frequency and delivering long-term protection.

FAQs
Yes. CVS3175X is a three-pole molded case circuit breaker built on the CV frame, designed for use in Eaton CV style load centers and standard low‑voltage panels. It accepts Cu/Al conductors #6-4/0 AWG, with terminals rated to #4/0 kcmil, and delivers up to 42 kAIC interrupt capacity at 175 A. This alignment simplifies retrofits and new installations.
CVS3175X is rated 175 A with a 42 kAIC interrupt capacity and provides three-pole protection in a CV frame. It uses #6-4/0 AWG Cu/Al conductors and supports #4/0 kcmil load at terminals, making it suitable for medium‑to‑large three‑phase circuits. The compact 7.5 in length, 5 in height, and 5 in width keep installation footprint manageable in most panels.
CVS3175X fits three‑phase low‑voltage protection tasks in load centers, motor control centers, and equipment panels across manufacturing and processing facilities. The 175 A rating and 42 kAIC interrupt capability handle typical plant fault currents, while the Cu/Al terminal options support flexible wiring strategies. Its compact size and CV frame compatibility ease retrofits and new installations in tight electrical rooms.
CVS3175X carries UL 489 and CSA compliance, confirming adherence to recognized safety and performance standards for molded case circuit breakers. These certifications simplify procurement, support regulatory audits, and align with typical electrical room requirements in North America. In practice, engineers rely on these marks to validate device suitability for panel assemblies, startup tests, and ongoing maintenance cycles.
With a limited lifetime warranty and a robust UL/CSA verified design, CVS3175X minimizes replacement frequency and extends service intervals. Its straightforward terminals and compact frame reduce installation and commissioning time, while the three-pole, 175 A rating handles steady fault protection without over-sizing equipment. For plant assets, this translates to lower total cost of ownership and improved uptime.
