BW series universal and enhanced protectors with large metal casing are composed of thermal conductive metal casing, bimetallic parts welded with silver alloy contact point, conductive bracket, insulation fixation stand, fixed contact strip, and heat resistance cable. In case of abnormal operation, when the environment temperature increases to the set value, the bimetallic parts perform quick action, open the contact point, and disconnect the circuit. When the device cools to the safe operating temperature, the contact point automatically closes and normal operation resumes.
BW series is applicable to chargeable batteries, ballasts, massagers, motors, transformers, electric tools, heat electric appliances, and instruments.
