MS-20D is a power surge protector; it is used for surge protection of commercial lighting power sources such as street lighting (ClassI ,ClassII ), landscape lighting, and surge protection for power ports such as security, electrical appliances, and sockets. TP20D has a fully sealedenclosure that is fire, water,dust and IP65 rated. The lightning protection device adopts full mode protection, adopts UVT technology, and has leakage current and freewheeling interruption function. The product is small and comes with L, N and PE cables for easy installation and application. The product's maximum protection lightning current is 20kA ,which can withstand 20kV surge voltage shock.

Advantage:MS-20D with a led indicator on it to tell you if the SPD works or not !

 Features:
• Resistant to Peaks and Surges of up to 20kA
• Class III Protection
• Maximum Surge Current = 20,000 Amps using industry standard 8/20 μSec wave
• Fully Sealed: Dustproof and Waterproof with IP Protection Grade: 65
• For use with Voltage up to 277V, 50/60 Hz. Power Supply
• High Temperature Enclosure: Up to 158°F (70°C) max. Surface Temperature Rating
•LED Indicator Instruction on the SPD:

(1)LED Indicator is lighted when SPD working normal.

(2)If LED indicator turn off,it means SPD has ended its life,and you have to replace a new SPD.
