How to choose the best suitable SPD Model ?
If the building has sub-distribution boards more than 10 metres away from the incoming panel, these boards will require additional protection. Usually a Type 2 surge arrester is sufficient here unless you are feeding outside final circuits, when a combined Type 1+2+3 surge arrester will have to be fitted.
Switching element
Mainly used in common mode protection, but also often used for differential mode protection in passive circuits.
Pressure limiting element
Mainly used in differential mode protection, it is also commonly used in common mode circuits in series with switching elements to prevent short circuit between the line and ground after the switching elements are turned on; or as a current limiting element of the switching element to block freewheeling and reset the switching element .
Shell material:
Using international brand nylon material and international brand PBT material, the bending strength is in accordance with GB/T9341-2008, and the impact strength of the simply supported beam is notched and unnotched. Comply with GB/T1043.1-2008, flame retardancy complies with GB/T2408-2008, excellent electrical insulation performance, and strong consistency of product surface technology.
