Special features
Basic
Two-module design with 200 kA per phase is a core feature that delivers high transient handling, reducing the likelihood of downstream damage to drives, PLCs, and motor controllers. This capability translates to fewer unplanned outages and lower repair costs, especially in high-load environments such as conveyors, pumps, and automated tooling lines in manufacturing facilities. NEMA 4 enclosure with an internal terminal breaker simplifies wiring and accelerates commissioning, while guarding against dust, moisture, and outdoor conditions. This rugged construction minimizes the need for additional enclosures or field components, delivering faster installations and fewer service calls for outdoor panels and harsh environments in manufacturing and utility settings. 277/480 VAC Wye (4W+G) compatibility ensures straightforward integration with common industrial feeders, reducing wiring changes and potential miswiring. The two-module configuration offers scalable protection that can grow with your facility while maintaining a consistent protection level across new and existing panels. RoHS compliance paired with UL 1449, UL 1283, and CSA notices provides regulatory assurance and safer installations across regions. The 15-year warranty, extendable to 20 years with registration, lowers lifecycle risk and total cost of ownership, making SPD MAX a prudent, cost-effective choice for mission-critical facilities like data centers and heavy manufacturing lines.

FAQs
The SPM200480Y1U is designed for 277/480 VAC Wye (4W+G) networks and supports a two-module configuration rated at 200 kA per phase. It’s enclosed in a NEMA 4 housing with an internal terminal breaker, enabling straightforward wiring to standard industrial panelboards and compatible Eaton SPD MAX installations. This makes integration with existing electrical infrastructures seamless and reduces rework during upgrades.
Key specifications include a 277/480 VAC Wye voltage rating, two modules, and 200 kA per phase protection. The device is RoHS compliant and carries certifications including UL 1449, UL 1283, and CSA notices. Its NEMA 4 enclosure with an internal terminal breaker supports rugged protection in industrial environments and streamlines installation and maintenance in manufacturing facilities.
Yes. The unit’s NEMA 4 enclosure is designed to withstand dust and moisture, making outdoor or harsh indoor environments feasible. With an internal terminal breaker, installation is simplified and maintenance activities are minimized. For outdoor panels, this SPD MAX series provides reliable transient protection without requiring extensive additional housing or components.
The SPD MAX SPM200480Y1U is backed by a warranty of 15 years from delivery, extending to 20 years if registered on Eaton’s SPD site. It carries regulatory certifications including UL 1449, UL 1283, and CSA notices, along with RoHS compliance, facilitating acceptance across regions and reducing lifecycle risk for mission-critical facilities.
Prioritize proper mounting in a suitable enclosure (NEMA 4), ensure correct connection to 277/480 VAC Wye feeders, and leverage the internal terminal breaker to minimize external wiring. Regularly verify RoHS-compliant components and maintain warranty registration to maximize the 15–20 year coverage. This approach reduces downtime, extends equipment life, and lowers total cost of ownership in data centers and manufacturing floors.
