The KAEL KA-SPD-4PAC Surge Protection Device (SPD) is a reliable solution for protecting electrical systems against transient overvoltages, lightning strikes, and power surges. Designed for three-phase AC systems, this 4-pole SPD ensures comprehensive protection across all phases and neutral, making it ideal for industrial, commercial, and residential installations.
With a nominal voltage rating of 480V AC, this device is built to handle high-power environments while maintaining system stability. It features a high surge handling capacity, typically up to 40kA, allowing it to effectively absorb and dissipate sudden voltage spikes before they can damage sensitive equipment.
The DIN rail mounting design enables quick and secure installation in distribution boards and control panels. Its compact structure saves space while ensuring easy integration into existing electrical systems. The SPD operates with fast response time, instantly clamping excess voltage to safe levels and maintaining uninterrupted system performance.
Built with durable materials and compliant with international safety standards, the KAEL KA-SPD-4PAC offers long-term reliability and protection. It is widely used in power distribution panels, solar systems, industrial machinery, HVAC systems, and data centers where equipment safety is critical.
