We are a trusted surge protection devices manufacturer in China specializing in manufacturing high-quality SPDs.
With a thorough understanding of standards and regulations, LSP manufactures millions of surge protection devices (SPDs) every year.
Our teams bring surge protection devices (SPDs) with our unique client-focused service & quality to the closest possible to the market demand.
20kA 40kA SPD is primarily designed for Type 2 surge protection device (SPD).
20kA 40kA surge protection device SPD SLP40 series is characterized by an 8/20 µs lightning current waveform.
Their nominal discharge current (In) is 20kA, and the maximum discharge current (Imax) is 40kA.
These 20kA 40kA surge protection device SPD SLP40 series are designed to be installed at the service entrance of low voltage systems or close to sensitive equipment to protect against transient overvoltages.

Max. continuous operating voltage Uc: 150V 275V 320V 385V 440V
Type 2 / Class II / Class C
Nominal discharge current (8/20 μs) In = 20kA @ Type 2
Maximum discharge current (8/20 μs) Imax = 40kA @ Type 2
Protective elements: Metal Oxide Varistor (MOV), Gas Discharge Tube (GDT)
The unique Trigger Release Technology forms independent chambers that effectively isolate and extinguish the arc during surge events.
By creating a physical separation space, this technology prevents the arc from spreading to other components or areas, thereby enhancing the safety and stability of the device.
TOP quality Metal Oxide Varistor (MOV) and Gas Discharge Tube (GDT)
Housing materials: PA 6 + 20%GF, flammability rating according to UL 94: V-0; Insulating material: PBT; Rockwell hardness 105 degree
Metal materials: nickel-plate 4μ, 48-hour salt spray test
