100 kAIC interrupt rating delivers strong transient suppression, reducing the risk of equipment damage and unplanned downtime while improving line reliability. This translates to measurable uptime improvements in manufacturing lines, packaging equipment, and motor control centers, supporting continuous production and lower maintenance costs. The external side mounting and NEMA 1 enclosure simplify retrofits and new installations alike, enabling quicker commissioning and safer servicing in control rooms and on factory floors. With a 230/400V wye (4W+G) configuration and defined operating voltages, the SPD integrates smoothly with standard industrial power networks, minimizing system rework and compatibility concerns. The Basic feature package keeps installation lean while maintaining essential protection against line-to-neutral, line-to-ground, and line-to-line surges, reducing total cost of ownership over the device lifetime. A 15-year warranty and UL 1449 compliance further reinforce long-term reliability and regulatory alignment, supporting compliance-driven procurement and reducing risk across data, automation, and process industries.
