High-energy surge protection with a 100 kAIC interrupt rating delivers immediate load protection and minimizes downtime. This translates to shorter repair cycles, safer operation, and fewer unscheduled outages for critical equipment. In practice it shields motors, drives, and PLCs in 277 V single-phase systems across industrial panels, improving overall uptime and production reliability. The device also features EMI/RFI filtering that reduces electrical noise, resulting in cleaner power delivery and extended device life. By combining filtering with robust surge suppression, it helps meet power quality standards in process automation environments while keeping installation straightforward for maintenance teams. External side mounting simplifies retrofits, enables fast integration, and supports standard panel layouts without extensive wiring changes, reducing field modification costs. The SPC series emphasizes durability and compatibility, delivering consistent performance in harsh environments with a long-term maintenance plan.
