Heavy-Duty Defense for Mission-Critical Power Systems
The SP-M100-385-4P is a premium 100kA 3-phase surge protection device (SPD) engineered for high-energy lightning environments. Designed with modular cartridges and zinc oxide varistor (MOV) technology, it safeguards sensitive industrial, telecom, and infrastructure equipment against severe overvoltages—while allowing fast replacement and maintenance to minimize downtime.
·Industrial-Grade Surge Suppression
With a discharge capacity of up to 100kA per line, this SPD offers robust protection for motors, drives, and power distribution cabinets in large-scale facilities. A built-in fuse and thermal disconnect mechanism provides multi-layer overload protection, while nanosecond-level response ensures that dangerous spikes are diverted instantly to ground before they damage connected loads.
·Smart Monitoring and Maintenance
The color-coded indicator window makes it easy to verify device health at a glance. An optional remote alarm contact supports continuous monitoring from control rooms or building management systems. Thanks to its modular plug-in design, faulty modules can be replaced without rewiring, ensuring both safety and long-term cost efficiency.
Applications
1.Telecom & Data Centers – Protect base stations, telecom racks, and server facilities.
2.Industrial Plants & Machinery – Safeguard motors, drives, and automation equipment.
3.Critical Infrastructure – Aviation, finance, and energy systems requiring uninterrupted uptime.
4.Power Distribution & Switchgear – Reliable defense for substations, cabinets, and panels.
