120 kAIC interrupt rating ensures robust transient suppression, protecting downstream equipment from high-energy surges. This directly reduces unplanned downtime and maintenance costs on critical lines, especially where motor drives and PLCs are exposed to spikes. Ideal applications include manufacturing lines, panel feeders, and control housings where fast-response protection preserves uptime and equipment life. 240V Delta voltage rating ensures the device aligns with delta-wired equipment, enabling seamless integration with motors, drives, and sensing networks. By matching voltage profiles, it minimizes nuisance tripping and reduces engineering time during panel upgrades. This makes it suitable for OEM builds and retrofit projects in process industries. The NEMA 4X enclosure provides reliable protection against dust, water, and corrosion in harsh environments. This enclosure resilience translates to longer service intervals, fewer field replacements, and better compliance with industry standards in chemical processing, food and beverage, and outdoor installations. It supports rugged operation on factory floors and remote control rooms. External side mounting simplifies integration into existing panels and enclosures, reducing install time and minimizing wiring complexity. This compatibility with SPC series configurations supports scalable protection across multi-line installations, allowing quick upgrades without retraining staff or reconfiguring downstream devices. UL 1449 certification and a 10-year warranty reinforce product reliability and vendor support. The combination helps meet corporate risk management and regulatory compliance while delivering predictable lifecycle costs for automation projects, plant maintenance programs, and facility upgrades.
