3-Phase Power Surge Protection Module/Power surge protector

Heavy-Duty Surge Protection for Three-Phase Power Systems

The SP-M40-385-4P is a robust surge protection device (SPD) engineered for industrial machinery, motors, telecom base stations, and power distribution cabinets. Designed with modular cartridges, it provides high-energy lightning and transient surge suppression while allowing quick replacement and maintenance—ensuring maximum uptime in mission-critical environments.

·High Surge Capacity with Rapid Response

Built to handle up to 40kA per line, the SP-M40-385-4P uses zinc oxide varistor (MOV) technology combined with a built-in fuse and thermal disconnect for layered defense. It responds in nanoseconds, diverting dangerous overvoltages to ground before they can damage sensitive equipment. A color-coded status window offers instant visual monitoring, while an optional remote alarm contact supports proactive maintenance across facilities.

·Modular, Safe, and Easy to Integrate

The plug-in modular design lets you replace only the damaged cartridge without rewiring, reducing downtime and maintenance costs. Standard 35mm DIN rail mounting ensures compatibility with distribution panels, while the flame-retardant housing improves safety in demanding environments.
