KW is a bimetal thermal switch with metal or plastic case. When temperature exceeds the specified value, the bimetal thermal switch would cut the circuit automatically to provent overheating. When the temperature is decreased down, the bimetal inside of the thermal switch would action again and close the circuit. Then, the applications can work properly again.

 

Application of bimetal thermal switch:

KW-3 is a metal case thermal switch with compact design. Main applications of KW are as follows:-

i) Motor, heaters, transformers

ii) Heating elements or heaters

iii) Juice extractor, and various sort of household appliances.

 

Specifications of bimetal thermal switch :

a) Function: Single-pole with contact opens when temperature range is reached.

b) Standard rating: [UL&CUL] 120VAC 5A [VDE&IEC&CB] 250VAC 8A / 24VDC 5A

c) Automatic Cycles for each automatic action : [UL&CUL] 6,000cycle

[VDE&IEC&CB] 10,000cycle

d) Maximum Temperature: [All standards] 150°C±5°C

e) Temperature range: [All standards] 50-150°C

f) Tolerance: [All standards] ±5°C

 

Special Features of bimetal thermal switch:

- KW is relative compact designed and is operated with 'Snap Action' which is sensed by current and temperature.

- KW can reset automatically after tripping off.

- KW can work in insulation liquid.
