surge protection type 3

type 3 spd surge protector

AC power SPD is mainly applicable to the power distribution systems for Class I / II / III( spd type 1 2 3 ) 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 power surge protection device is single-phase or three-phase, ac spd 4 pole or multi-pole, with slightly different 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.

Type 1+2 /Class B+C Switch-type Lightning Surge protectors

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.

Type 2/Class C protection DIN-rail Pl able 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.
