320 kA per phase with a two-module design delivers aggressive transient suppression, significantly reducing downstream damage to breakers, PLCs, and motor controls. This improves uptime and asset longevity in demanding environments such as machine rooms and data centers. 120/208 V Wye (4W+G) compatibility ensures seamless integration with common power systems, enabling faster project timelines and lower total cost of ownership. The NEMA 4X enclosure with internal terminal block provides weather and corrosion resistance alongside safer, neater field wiring, supporting easier retrofits and reduced commissioning time. A built-in surge counter enables proactive maintenance and audit-ready reporting, aligning with safety programs and regulatory requirements while RoHS compliance streamlines supplier qualification. A 15-year warranty, extendable to 20 years when registered, reduces ownership risk and reinforces long-term protection for critical loads.

FAQs
Plan for a standard installation in a controlled electrical space with the NEMA 4X enclosure. Use the internal terminal block for field wiring, verify correct phase connections for a 4W+G configuration, and ensure adequate clearance for servicing and the optional surge counter. The two-module design supports scalable protection without rewiring existing panels.
A 320 kA per phase rating means the device can absorb large transient surges before clamping and dissipation. This reduces the likelihood of insulation damage, nuisance trips, and downstream electronics failures in motors, drives, and control circuits, especially during grid disturbances or lightning events typical in industrial facilities.
Yes. The enclosure is rated NEMA 4X with internal terminal block, designed to withstand harsh environments. This allows installation in outdoor-rated electrical rooms or semi-exposed indoor locations, while maintaining safe wiring access and protection against dust, rain, and corrosion when properly mounted.
The unit carries UL 1449, UL 1283, and CSA certifications, along with RoHS compliance. These approvals confirm electrical safety, electromagnetic compatibility, and material restrictions meet North American regulatory standards, simplifying audits, supplier qualification, and project approvals for regulated industries.
Eaton offers a 15-year warranty, extendable to 20 years when registered. The built-in surge counter supports proactive maintenance planning, reducing unexpected downtime. Together, these factors lower total cost of ownership by stabilizing asset protection, minimizing replacement cycles, and improving equipment uptime across multiple sites.
