Eaton CVS3175X3 Molded Case Circuit Breaker - 42 kAIC
Part Number: CVS3175X3
Quick Summary
Molded Case Circuit Breaker protects industrial power systems by interrupting fault currents in main distribution panels. This CVS3175X3 unit is designed for CV frame installations where reliable main protection is critical. Operators upgrading from smaller devices often struggle with nuisance trips, wiring complexity, and limited conductor options. The CVS3175X3 delivers decisive current interruption at 175 A with a 42 kAIC rating and is UL 489 and CSA Std. C22.2 No. 5 certified for compliance. With a limited lifetime warranty and CV-compatible terminal arrangements, it streamlines procurement and reduces total cost of ownership. Secondary considerations include easy field wiring up to #6-4/0 AWG and support for large feeders, delivering safer, more predictable protection in load centers and switchgear.

FAQs
The CVS3175X3 is designed for CV frame distribution panels and related low-voltage switchgear. It accepts up to #300 kcmil conductors with an optional terminal shield, features three-pole protection for three-phase systems, and fits within the standard 11.5 inch depth. Ensure installation in UL 489 compliant assemblies for code conformance.
The device provides a 175 A continuous rating and a 42 kAIC interrupt rating, enabling rapid fault clearance and minimizing damage to feeders and equipment. Its three-pole design supports proper three-phase protection, improving fault isolation and system reliability in industrial power distributions.
Yes. The CVS3175X3 carries UL 489 and CSA Std. C22.2 No. 5 certifications, confirming compliance with U.S. and Canadian electrical codes. These certifications support safe operation in critical facilities, streamline procurement, and help meet regulatory requirements for electrical protection devices.
Its compact footprint and standard CV frame wiring options simplify installation and reduce field wiring time. With a limited lifetime warranty and readily available spares from Eaton, maintenance intervals can be extended, downtime minimized, and total cost of ownership improved for plant protection systems.
When using 300 kcmil feeders, plan for the terminal shield which adds 1.5 inches to the breaker length. This ensures safe terminations, correct clearance, and proper insulation in high-capacity feeds while maintaining CV frame compatibility and compliance with associated wiring codes.
