Product Description

TOPRO BW9700 series thermal protectors adopt bimetal discs that bend with the temperature changes as the temperature sensing element. Without other auxiliary structures, only by the temperature sensing ability of the bimetal disc itself and the electrical heat effect, when the ambient temperature rises to the preset operating temperature, the bimetal disc snaps quickly to break the circuit automatically. When the electrical appliance is cooled down to the reset temperature, the bimetal disc bends back to connect the circuit, thus protecting the electrical appliance from overheat and overload.

TOPRO BW 9700 series thermal protectors are featured by advanced bimetal disc structure, miniature size, snap action, large contact capacity, and long service life. They are widely used for overheat and overcurrent protection in various electric motors, electromagnetic oven, vacuum cleaner, air conditioner motor, solenoid, transformer, electrical heater, electrical heating appliances, fluorescent ballasts, automobile motors, integrated circuits and common electrical appliances.
