FAQs
To install the CVS3225W, verify the panel accepts a CV frame unit and that space accommodates a three-pole breaker. Note that terminals are not included, so plan for suitable lugs or a field-installed lug kit. Ensure proper torque on terminations, follow CE/UL guidelines, and allow clearance for ventilation. This approach minimizes retrofit risk and supports compliant, fast upgrades in existing switchgear.
Key specs include a 225 A rating and a 42 kAIC interrupt capacity, enabling reliable interruption of high fault currents. The three-pole design supports three-phase systems, and the CV frame ensures matched physical and electrical compatibility with Eaton panels. Wire sizing of #6-4/0 Cu/Al expands feeder options while maintaining safe termination practices and coordination with downstream protection devices.
Yes. The CVS3225W is well suited for industrial automation panels, control cabinets, and load centers that require robust three-pole protection. Its 225 A capacity handles substantial automation loads, while the 42 kAIC rating preserves system safety during short-circuit events. The CV frame design supports straightforward integration into CV-based panels used in manufacturing environments.
The CVS3225W carries UL 489 and CSA Std. C22.2 No. 5 certifications, ensuring compliance with essential electrical safety and performance requirements. This matters for meeting electrical code mandates, ensuring installation approvals, and facilitating system acceptance in regulated facilities. These certifications also reassure maintenance teams about device reliability and warranty coverage in demanding industrial settings.
The unit carries a limited lifetime warranty, supporting long-term reliability in critical power paths. ROI benefits come from reduced downtime due to robust fault interruption (42 kAIC) and a durable CV frame design that minimizes replacement frequency. Compatibility with standard Cu/Al feeders and a terminal-free setup further reduce field labor and inventory costs during upgrades or expansion projects.
