Special features
Basic
160 kA per phase surge capability translates to superior protection for critical loads, reducing nuisance trips and downstream equipment damage. This translates into measurable uptime gains and lower maintenance costs in manufacturing lines, data centers, and control panels where high-energy transients are common. The 277/480 V Wye configuration ensures compatibility with standard plant power distribution, minimizing the need for transformers and simplifying panel design. A single-module MAX format reduces install footprint while enabling quick upgrades to existing protection schemes. The NEMA 4X enclosure with an internal terminal block streamlines installation, wiring, and field service, enhancing reliability in harsh environments. RoHS compliance and listed certifications provide regulatory assurance and support for sustainability reporting. The 15-year warranty (20 years with on-line registration) extends asset life and lowers lifecycle risk, supporting a favorable total cost of ownership (TCO) profile for capital projects.

FAQs
Install the device within a suitable panel or enclosure that accommodates a NEMA 4X rated housing. Connect the three phase lines and ground to the internal terminal block, following the included Eaton installation sheet. Verify clearances, torque values, and proper grounding; ensure coordination with upstream protective devices and that the unit is slotted for easy future maintenance.
The 160 kA per phase rating indicates the maximum transient energy the device can safely divert per phase without compromising protection or performance. This rating translates to higher resilience against large lightning and switching surges, reducing the probability of downstream equipment damage, nuisance tripping, and insulation stress in critical loads.
Yes. The 277/480 V Wye configuration and robust 160 kA per phase protection make it suitable for data centers, manufacturing lines, motor drives, and PLC-controlled systems. Its NEMA 4X enclosure supports harsh environments, while UL/CSA certifications and RoHS compliance ensure regulatory alignment for mission-critical facilities.
The unit is listed to UL 1283 and UL 1449 standards, and also aligns with CSA electrical notices and standards. It is RoHS compliant, ensuring restricted hazardous substances in line with EU and international requirements. This combination supports regulatory acceptance in North American and global installations.
Eaton provides a 15-year warranty from the date of delivery, with a 20-year warranty available when the unit is registered on Eaton’s SPD site. This extended coverage reduces maintenance risk and supports long-term asset protection, complementing the device’s durable NEMA 4X construction and RoHS-compliant design.
