3.4 Insulation voltage:
a. The thermal protector should be able to withstand AC660V, 50Hz alternating current between the two leads after thermal disconnection. Test lasted 1min, no breakdown or flashover;
b. The terminal wire of the thermal protector and the surface of the insulating sleeve or the surface insulating type thermal protector shell can withstand AC1800V, 50Hz alternating current. Lasted 1min, no breakdown or flashover;
3.5 절연저항: Under normal conditions, the insulation resistance between the wire and the insulation sleeve is above 100MΩ. (The meter used is a DC500V insulation resistance meter)
3.6 접촉 저항: When the thermal protector is closed, the contact resistance should not be greater than 50mΩ.
3.7 Heat resistance test:The product is placed in a 150°C environment for 96 hours.
3.8 Moisture resistance test: The product is placed in an environment at 40°C and a relative humidity of 95% for 48 hours.
3.9 Thermal shock test: The product is placed alternately in a 150℃, -20℃ environment for 30min each for 5 cycles.
3.10 Vibration resistance test: The product can withstand amplitude 1.5mm, frequency change 10~55HZ, scanning change period is 3~5min. Vibration direction X, Y, 지, continuous vibration for 2 hours in each direction.
3.11 Drop test: The product falls freely once from 200mm height.
3.12 Compression resistance: Custom thermal protector products that require vacuum impregnation are immersed in a sealed oil tank. After applying 2Mpa of pressure and keeping it for 24h.
3.7,3.8,3.9,3.10,3.11,3.12 After the test, the following conditions shall be met:
