FAQs
CVS3090 uses the CV frame type and three‑pole configuration, designed to drop into standard CV‑frame installations. It features #6-4/0 kcmil line/load terminals compatible with Cu/Al conductors, supporting straightforward wiring and fast field upgrades. When pairing with Eaton accessories, you gain streamlined expansion in panel boards and power distribution centers while preserving conductors and torque specs.
CVS3090 is a 90 A molded case circuit breaker with a 42 kAIC interrupt rating. It is a three‑pole device, designed for three‑phase protection in main distribution applications. The combination of 90 A rating and 42 kAIC helps limit fault energy and protects feeders, motors, and downstream protection devices in typical industrial panels.
Ideal for industrial control panels, distribution boards, and motor control centers requiring reliable main protection in three‑phase systems. Use cases include manufacturing lines, water/wastewater facilities, and processing plants where UL 489 and CSA certifications ensure compliance, and a compact 7.5 in length footprint enables dense panel layouts with compliant protection.
The CVS3090 carries UL 489 and CSA Std. C22.2 No. 5 certifications, validating safe operation and regulatory compliance for low‑voltage distribution equipment. These certifications reduce risk during audits, support NEC/IEC alignment, and provide documented reliability for preventive maintenance programs in regulated facilities.
CVS3090 offers a limited lifetime warranty, reflecting Eaton’s confidence in long‑term performance. Maintenance considerations are standard for molded case breakers: periodic testing, inspection of terminals for tightness, and replacement after sustained fault events. ROI comes from reduced downtime, fewer nuisance trips, and simplified panel upgrades driven by robust protection and long service life.
