1-Phase Power Surge Protection Module/Power surge protector

Protect Critical Single-Phase Power Lines from Lightning and Overvoltage

The SP-M40-385-2P safeguards sensitive single-phase equipment against high-energy lightning strikes and transient surges. Built for telecom base stations, industrial plants, control cabinets, and financial systems, this modular SPD provides reliable suppression where uptime and safety are mission critical.

·Engineered for High Surge Capacity and Rapid Response

With a discharge capacity of 40kA, the SP-M40-385-2P delivers robust surge handling, ensuring your systems stay online even during severe electrical storms. Using zinc oxide varistor (MOV) technology combined with a built-in fuse and thermal disconnect, it reacts in nanoseconds to safely divert excess energy to ground. The color-coded status window offers instant visual feedback, while an optional remote alarm contact enables proactive monitoring from a central control system.

·Modular, Easy to Install, Simple to Maintain

The SP-M40-385-2P adopts a modular cartridge design, allowing quick replacement of surge modules without disturbing the wiring base—minimizing downtime and maintenance costs. Its 35mm DIN rail mount fits standard distribution boards and cabinets, while the flame-retardant housing ensures safety and long service life in demanding environments.
