Varistor Voltage
The voltage between two terminals with the specified measuring
current CmA DC applied is called Vc or VCmA. The measurement shall
be made as fast as possible to avoid heat affection.
Maximum Allowable The maximum sinusoidal wave voltage (rms) or the maximum DC

Vibration
After gradually applying the load of 49 N (5 kgf) and keeping the
unit fixed for 10 seconds in an axial direction, the terminal shall
be visually examined for any damage.
