MLY1-A25 4P Type1 SPD with 25kA impulse current, installed at distribution main inlet to dissipate direct lightning current. It limits surge overvoltage and protects back-end electrical devices. DIN rail mounted, ideal for building, PV and industrial power lightning protection.
MLY1-A25 is a 4P Type 1 surge protective device, designed for the front-end lightning protection of low-voltage power distribution systems. It adopts 10/350μs impulse current waveform test standard, which can release the huge energy of direct lightning strike, limit transient overvoltage and protect the electrical equipment behind the circuit from lightning surge damage.
This SPD adopts integrated modular structure, high-strength flame-retardant housing. It is installed on standard 35mm DIN rail, easy to mount inside distribution cabinets. It is widely used in the main incoming cabinet of buildings to realize primary lightning protection for power supply system.
Suitable for main power incoming cabinets of commercial buildings, industrial workshops, photovoltaic power stations, large residential districts and data rooms. It serves as the first-level lightning protection in low-voltage power distribution system.
