The Surge Pure M4-1480-3 is a robust, primary-level surge protective device (SPD) intended for service entrances and main distribution panels in 3-phase Delta AC systems, supporting a maximum service size of 800 A. This unit is built with an integral grid of non-degrading SPD technology to provide continuous, long-term AC power system integrity. Its high-energy, non-degrading surge capacity is designed to function as a vital, initial defense against severe power system disturbances, forming the basis of a comprehensive, layered protection grid when combined with other units.
In plain terms, the device functions to isolate sensitive downline equipment from both external utility hazards, including transient voltage from lightning and severe switching events, and internal power surges caused by electrical switching loads within the facility. With a Total Surge Capacity of 420 kA (at 8x20 µsec pulse) and a Max SE* Surge Current Per Mode of 80 kA, the unit effectively diverts harmful energy across L-L modes to protect connected equipment.
For install fit, the M4-1480-3 is housed in a durable indoor/outdoor (NEMA 4X) enclosure, signifying dust, drip, hosedown, and corrosion-proof capability. The Overcurrent Protection note states: Type 1 & Type 2, no breaker required / for fast easy panel installations, use 30 amp breaker - CODE RULE 26-420 (2). The device is c-ETL-us Listed and Certified to the latest UL 1449, 5th Edition, ensuring compliance with industry safety standards and achieving the highest safety SCCR rating of 200kAIC. Always follow local electrical code and use a qualified electrician where required.
When choosing this model, verify that your system is a 3∅ Delta AC service with a nominal AC line voltage of 480 VRMS and 50/60 Hz frequency. Key performance metrics include the Max Continuous Operating Voltage (MCOV) of 550 V and a Max. Clamping Voltage L-L of 1175. The device comes with a lifetime manufacturer's warranty, and its protection status is confirmed via the Lifetime Green LED Self Test 'Protection Status Monitors' for each phase.
