1 产品用途Application
HKW9700-B-C型热保护器具有体积小、外壳绝缘、动作灵敏、寿命长等特点，
适用于新能源电池，电机、电源，光灯镇流器、变压器、汽车马达、集成电路及
一般电气设备的过热过流双重保护作用。
HKW9700-A-B-C thermal protector has small dimension; insulation shell;
sensitive and long life time. Its widely use in new energy battery;
motor; power; ballast; transformer;integrated circuit and
electrical equipment’s overheat and overload double protection.
2 结构特点Structural features
HKW9700-B-C系列热保护器是采用一定几何形状的双金属片，无需辅助机构，仅靠双金属片的自身感温和电流热效应，使双金属元件的状态发生快速变化，直接带动触点实现自动切断和接通电路，起到过热、过载保护作用。
HKW9700-A-B-C thermal protector use unique bimetal and don’t need more auxiliary parts. Using bimetal Self-sensing temperature and Current thermal effect to change the bimetal’s shape to control the electric circuit cut off or contact on. Overheat and overload double protection.
