How To Choose A Composite Surge Protector Manufacturer?

How to choose a composite surge protector manufacturer? When many friends choose to buy a surge protector, they generally pay attention to the technical parameters of the selected model and the price of the product, but often do not care about the product type of the surge protective device itself. However, it is actually more important to choose a surge protection device with excellent internal structure and better working performance! Since the T1-level surge protector has strong tolerance, can withstand (10/350μs) waveform impact test, and has a large discharge capacity, there are generally two types: composite surge protector and switch surge protector. So why do so many people choose composite surge protectors?

1. Components used by composite surge protector manufacturers

The composite surge protector is composed of a discharge gap and a voltage limiting element (MOV) in series, and its characteristic is no continuous current; while the commonly used components of the voltage switch surge protector are discharge gaps, gas discharge tubes (GDT), etc., which have continuous current.

2. Working status of composite surge protector

3. According to the requirements of UL1449, the surge protector must meet the following requirements:

(1) No continuous current

(2) The primary surge protector itself must be able to withstand the short-circuit withstand test, without the help of other overcurrent protectors (such as fuses, circuit breakers, backup protectors, etc.).
