1. The thermal motor protector TM1 is an electro-mechanical safety device, which provides complete protection to your electrical equipments against overheating and overloading and mechanical malfunctions. The contacts close again automatically, as the device cools down.

2. Because of the very small size and high compressive strength it specially can be used for direct fitting in coils of motors and transformers.

3. The thermal motor protector TM1 is single pole and operates independent from any current supply. Contact configuration has two modes: normally closed (NC) or normally open (NO).
