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.
Stamping:
It is made of high-precision copper, and the screws and locking
sleeves are electroplated after heat treatment. The advantage is
that the product is not easy to slip, the salt spray test can reach
72 hours, and the plugging force is moderate.
Elaboration
1. It is recommended that the maximum flow of SPD Imax: 10-60KA.
2. It is recommended that SPD be used in an environment of -40℃ to +100℃.
3. 1P, 2P, 3P, 4P can be distributed according to demand to meet various needs.
4.35mm guide rail design is convenient for subsequent installation.
