This causes energy to be dissipated in the MOV and eventually causes it

Product Testing
Standard UL 1449 is widely regarded as the standard imposing the mostStandard UL 1449 is widely regarded as the standard imposing the most
stringent test requirements to ensure product safety.
It has three types of Abnormal Overvoltage tests, that involve applying the yp g pp y g
overvoltage, and limiting the following current to different values to
ensure correct operation over a wide range of conditions:
1) Low current: 5A to 10A (we use THERMAL FUSING)
2) Intermediate Current: 500A to 1000A (we use OVERCURRENT FUSING)
3) Maximum Current: Manufacturer decides how high to go. We have
chosen to go to the maximum – 200,000A (we use OVERCURRENT
FUSING).
