Test Method

Use the device which has been left for 15 minutes or more in 25°C

set voltage to be applied to the element at maximum rated voltage.

And set current to be applied within the range between trip current

and maximum rated current

Without damage under 24 hours

of current sending

Trip Endurance

Use the device which has been left for 15 minutes or more in 25°C
