Performance
The Max tripping electrical parameters
250VAC 3A / 127VAC 6A, 12VDC 6A / 24VDC 5A.
The tolerance of action temperature:±5℃, the reset temperature
according to actual
setting requirements.
Insulation voltage: The thermal protector can should be able to
withstand AC1500V,
1min or AC1800V,1s between lead wire and insulation sleeving, no
breakdown
flash-over phenomenon, the leakage current should be below 1mA.
Insulation resistance: Under normal conditions, the insulation
resistance between lead
wire and insulation sleeving is more than 100MΩ(The meter used is
DC500V insulation
resistance gauge).
Contact resistance: The contact resistance of thermal protector
should be less than
50MΩ.(Or customized)
Heat resistance test: The product is placed within 150℃ environment
for 96 hours;
Humidity test: The product is placed at the 40℃ environment with
the relative humidity
of 95% for 48 hours.
Drop test: the product drops freely once from a height of 70cm to
the ground(plastic or
wood floor).
Life Cycles
Under the conditions of the rated voltage, current and power factor
of 1, a heat source is
added to the product to make it move for 2000 times, which should
meet the following conditions:
A: The action temperature should change within ±5℃ of the initial
value;
B: The contact resistance should be less than 50mΩ;
C: No welding or shedding of electrical contacts;
D: After the product continues to be tested for 10,000 times, its
action to be normal and
correct.
