We  keep  in  researching  and  developing  high-tech  and  innovative  bimetal  thermostat,  thermal  protector,  thermal  switch,  thermal  cutout,  and  capillary  thermostat  with  reliable  quality. Hotline:0086 13924337782

6APE is a DC series current sensitive thermal protector. They can protect motor of window lift or wiper from over loading and will disconnect the power supply in few seconds.  It is widely used in automotive industry, like window lift, wiper, skylight motors and so on.

3MPE is an AC series current sensitive thermal protector.  It is supposed to protect AC motors, lightings, juicers, blenders or other AC applications from overloading. When the current flow through this protector exceeds the specified value, the protector would action quickly and cut the power off in shor time.

* Special Features of thermal protectors:

1. Current sensitive, Min trip off current: 1.2A; Max trip off current: 42A
2. Small size, long life and high reliability
3. High quality level bimetal ensures that it can withstand the current of normal circuit.
4. The combination of bimetal and heater can action snappily.
5. Accurate trip off time can prevent motor from overheating or loading;
6. Both temperature and current sensitive.
7. Terminals are optional and customizing
8. Wires are optional and customizing
