FAQs
The CVS3175Y3 is a three‑pole unit rated for 175 A with a 42 kAIC interrupt rating and accepts conductors up to #6-4/0 Cu/Al. When using #300 kcmil options, install a terminal shield and add 1.50 inches to the breaker length as noted in catalog guidance. Ensure proper torque on all terminations and verify UL 489/CSA compliance during panel assembly.
With a 42 kAIC interrupt rating, the CVS3175Y3 can safely interrupt high fault currents without sustaining excessive damage, preserving downstream equipment and reducing arc energy exposure. This makes it suitable for medium‑to‑high fault scenarios in distribution panels and motor feeders, improving overall system reliability and safety.
Yes. The three‑pole CVS3175Y3 fits standard load centers and motor control circuits, offering 175 A protection and robust short‑circuit interruption. Its CV frame and conductor range support common industrial wiring schemes, enabling seamless integration into panelboards and motor starter assemblies while complying with UL 489 and CSA standards.
The CVS3175Y3 is certified to UL 489 and CSA Std. C22.2 No. 5, confirming conformance with North American electrical protection and safety requirements. Compliance simplifies code approvals, procurement, and warranty processes, particularly for regulated facilities and projects targeting NEC/IEC alignment.
The breaker carries a limited lifetime warranty and is designed for long‑term reliability in industrial environments.
