Eaton CVS2150W CV Molded Case Breaker - UL 489, 42 kAIC
Part Number: CVS2150W
Quick Summary
Eaton CVS2150W CV Molded Case Breaker provides reliable overcurrent protection for electrical panels and distribution gear. It is designed to prevent nuisance trips and coordinate protection across feeders in commercial and light industrial installations. Engineers often wrestle with limited interrupt ratings, installation complexity, and compatibility gaps when upgrading panelboards. This device carries UL 489 and CSA certification for compliance, a 42 kAIC interrupt rating for high fault conditions, and uses the CV frame to simplify replacement in existing Eaton systems. Designed for load centers and industrial control panels, it supports #6–4/0 AWG copper or aluminum conductors and offers a compact footprint that saves panel space while preserving reliability. The limited lifetime warranty and Eaton service ecosystem further reduce lifecycle costs.

FAQs
CVS2150W is a two-pole CV frame molded case breaker intended for CV frame systems. It is supplied without terminals, so you must provide compatible lugs or terminal assemblies per CV frame guidelines. It supports #6-4/0 AWG Cu/Al conductors, enabling field-terminated configurations that preserve UL 489/CSA compliance. Always verify terminal compatibility with the specific CV load center model in use.
Key specs include a 150 A rating and 42 kAIC interrupt capacity, two poles, and a CV frame. These parameters inform protection coordination, allowing you to select upstream devices and settings that isolate faults quickly without nuisance tripping. The UL 489 and CSA certifications further ensure the device meets prevailing safety and electrical codes for panel installations.
CVS2150W is well-suited for load centers, panelboards, and industrial control panels in commercial facilities, data centers, and light manufacturing. Its CV frame design supports straightforward replacement in existing Eaton CV systems, while the conductor range and 150 A rating accommodate typical branch-circuit protection needs with robust fault handling.
CVS2150W carries UL 489 and CSA Std. C22.2 No. 5 certifications, confirming safety and performance to widely adopted standards. The 42 kAIC interrupt rating enhances protection in higher fault environments, supporting code compliance, safer installations, and smoother acceptance by inspectors and utilities.
The CVS2150W benefits from a limited lifetime warranty and Eaton’s service network, reducing lifecycle risk. Its compact footprint and terminal-less configuration shorten installation time and save panel space, contributing to faster retrofits, lower labor costs, and improved ROI in protection schemes for commercial and light industrial applications.
