AC Power Surge Protector/Protection Device, AC SPD Type 123 for Sale| Techwin

AC Power SPD, also known as ac power surge protector, 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.

As a professional SPD supplier with 15 years of experience in lightning protection solutions, Techwin offers AC surge protection devices with superior performance parameters, ensuring reliable protection in strict compliance with industry standards. Additionally, Techwin provides OEM and ODM services to meet the customized needs of various customers.
