* Connection Type: 250 male terminal
* Shell: Black plastic shell.
* Electric Strength: The overload protector can withstand AC 50-60HZ in short circuit, the test voltage is 250V RMS value 400A or 125VAC/1000A without breakdown and flashing, and it is naturally disconnected.
* Contact Resistance:The contact resistance of protector should be less than 80MΩ
* Life Cycle:The overload protector is at 50HZ-60HZ. Voltage 250V. Under the condition of power factor COS∮=0.5, it is 6 times of rated current. After 50 times tests, the rated breaking time is 5-40sec at the initial value, Contact does not weld,After high voltage 1500V / 1 minute without breakdown, the current protector should still work reliably after 50 times tests.
