The 2BM Motor Protector is a manually reset protector designed to provide extremely fast tripping response in the event of prolonged overload, rotor lock, undervoltage, high ambient temperature, or poor ventilation. It prevents motor overheating by automatically disconnecting the circuit. The device is widely used in pneumatic motors, motor pumps, commercial and industrial motorized equipment, food waste disposers, oil furnace motors, power tools, vacuum cleaners, and other applications.

The TS01 button-type snap-action protector is a compact bimetallic thermostat. Utilizing the principle of instantaneous snap-action of a disc-shaped bimetallic strip under temperature influence, it drives rapid contact movement via its mechanism to achieve circuit disconnection or connection.
