1.professional surge protector for ac power 2.working voltage: 220V /380V AC 3.1,2,3,4P(+NPE) 4.ISO9001 5.8 years experience

3 Level Power-supply Module (4P,3P+NPE) surge protector for ac power 

1. Third level protection

2. install in the frond of the equipment 

3. limit the overvoltage under the equipment’s overvoltage resistance level  

 

Feature:

D level surge protection, low residual voltage, quick response, standard guide rail design, standard plug-in modular design, easy installation, simple maintenance, module degradation indication, automatic switching off at exit failure and recovery, do not affect the normal power supply.
