AC Surge Protector, AC Surge Protection Device (SPD) Type 1 2 3

SPD for AC Power Supply is mainly applicable to the power distribution systems for Class I / II / III( Type1, type 2, type3) protection. Surge arresters for AC line units can protect electrical equipment from the impact of lightning electromagnetic pulse, induced over-voltage, transient operation, and resonance(＜100μs) overvoltage. Common AC surge protection devices (SPD) are single-phase or three-phase, 4 poles or multi-pole, with slightly different ac spd prices.

Type 1/ Class B Lightning Surge Protection for AC Power Systems
Type 1 AC power SPD series power supply system AC module are mainly appicable to power distribution system for class I / type 1 protection.
Type1+2/ Class B+C SPD MA25 series
These series products are mainly used for Type 1+Type 2 protection of power distribution systems (10 / 350µs) and are used to protect electrical and electronic equipment from the damage of lightning electromagnetic pulse induced voltage, operating transients, and resonance (<100µs) overvoltage.
Type1+2/ Class B+C SPD MA25S series
As switch-type SPD technology advances, the follow current interruption capability (Ifi) is improving too. Our company uses gap technology to enhance the performance of our switch-type SPD and has developed the MA25 and MA25S series products with outstanding follow current interruption capability.
T1+T2/Class B+C Combination type Surge Protection Device
Compound surge protection devices (SPDs) are advanced surge protection systems designed to provide enhanced protection against transient overvoltages and surges in electrical systems.
Type 2/Class C protection DIN-rail Pluggable AC surge protector
Type 2 AC power supply system AC module is mainly applicable to the power distribution system for class C/type 2 protection, to protect electrical equipment from the impact of lightning electromagnetic pulse, induced over-voltage, transit operation, and resonance (less than 100 μs) overvoltage.
