FAQs
Consider mounting space for a 14.91 inch wide by 17.5 inch high enclosure, ensure adequate clearance for venting and terminal access, and plan for an internal terminal breaker to simplify wiring. Confirm your panel can accommodate 9.3 inch depth and a 50 lb unit weight, and verify compatibility with 240 delta (4W+G) configurations.
A 400 kA per phase rating provides robust transient clamping for high-energy surges, reducing the likelihood of equipment damage in mission-critical applications such as motor drives and switchgear, and delivering greater uptime in environments with frequent transients or grid instability.
Yes. The device is designed for 240 delta (4W+G) configurations, enabling straightforward integration into four-wire high-leg delta systems and ensuring proper protection without compromising system functionality or L-G/L-N references.
The unit carries UL 1283 and UL 1449 listings and CSA certification, with RoHS compliance. These attest to safety, performance, and environmental standards, aiding procurement approvals and reducing compliance risk in regulated industries.
The 15-year warranty (20 years with registration) lowers lifecycle risk and maintenance frequency, while the durable NEMA 4 enclosure and internal breaker simplify installation and service. Reduced downtime and longer asset life translate to lower total cost of ownership for industrial protection solutions.
