high voltage surge protector zinc metal oxide varistor surge arrestor surge absorber 40mm 40D471K surge protector movs

1.      Ceramic Disc: Zinc Oxide Varistor

2.      Material of coating: Epoxy resin

3.      Material of Leads:  CP wire

4.      Lead type: Straight lead

5.      Package: Bulk pack

 1. Varistors Voltage: The voltage between two terminals with the specified measuring current 1mA DC applied is called V1mA,The measurement shall be made as fast as possible to avoid heat affection.  

 4.Clamping Voltage:The peak voltage at class current (Standard surge currentwaveform is 8/20μS).  The class current is a peak value of current which is1/10 of the maximum peak current for 100 impulses at per minute for 8/20μS.  

 12. Robustness of Terminations:

After gradually applying the force specified below and keeping the unit fixed for ten seconds. The terminal shall be visually examined for any damage.

Lead diameter(mm):   0.6   0.8   1.0   Force  (N):             1    10    20

13.Shock(or bump):

Pulse shape half sine acceleration:490 m/s2.Pulse duration:11ms.

Thereafter, visual examination and the change of  V1mA  shall be examined.

14.Virbration:

Frequency range:10Hz--55Hz.Amplitude: 0.75mm or 98 m/s2whichever is the less severe.Total duration: 6 hours .Thereafter, visual examination and the change of  V1mA  shall be examined.
