External side mounting and a stainless steel enclosure provide durable installation options while resisting harsh environmental conditions; this reduces field service time and maintenance interruptions, delivering lower total cost of ownership in manufacturing and process environments. The 100 kAIC interrupt rating translates to robust transient handling, protecting downstream drives and controls during severe surges and helping keep uptime high in motor control centers and distribution panels. Operating at 240V delta (4W+G) ensures compatibility with common industrial power architectures, enabling seamless integration with backup power systems and VFDs without custom wiring. The standard feature package plus a built-in surge counter simplifies monitoring and compliance reporting, supporting proactive maintenance and faster fault isolation in plant floors. UL 1449 listing and a 15-year warranty back up long-term protection, reducing risk and warranty costs while aligning with strict industry standards for electrical protection. Compatibility with SPD accessories and mounting options enables scalable protection across multiple enclosures, from small switchgear to larger distribution assemblies, delivering a modular, maintenance-friendly protection strategy for facilities with evolving power protection needs.
