17AMH / 17AMH+PTC thermal protector’s Principle and structure

17AMH thermal protector is an excess-current thermal protector with compact design, Quick and accurate action, we can rivet different types of leads according to customers' requirements.

17AMH+ PTC thermal protection, in 17AMH thermal protector on the base of the PTC heating element is installed inside, due to the electrical work is not normal, causes the surrounding temperature, when the heat reaches disconnect the temperature protector, bimetallic strip quickly jump action, make the two off contact, to cut off the circuit. While at the same time due to the broken touch point on the voltage applied to the PTC heating elements, generate enough heat to keep bimetallic strip continue to jump, only when to cut off the power supply can contact closure.

17AMH / 17AMH+PTC thermal protector’s application

17AMH thermal protector is applicable to all kinds of Motor, commentator for fluorescent lamp, transformer, Laminator, lamps and lighting, transformers, cover sealing machine & several of household appliances
