TECHNICAL SPECIFICATION
FOR THERMAL PROTECTOR 7AM
1 APPLICATION
7AM series have the characteristic of small size, insulated shell, high sensitivity and long life. They are
widely used in the dual protection of over-heat and over-current for fractional horsepower motor, electric
heating appliances, ballast for fluorescent lamp, transformer, motor, IC and general electrical equipment.
