Batteries Thermal Protector

Detailed Product Description

Product description

KI-67 series thermal protector is made up of heat conductive metal shell, bimetallic components welded with silver alloy contact, electricity onductive holder, insulated fixed base, static contact piece and heat resistant leads, etc. When the current goes through the bimetal components with impedance, if the current rises or the environmental temperature rises to the preset value, the bimetal components will work immediately   and release the contacts to shut off the circuit. By contrast, when the device cools down to the safe temperature, the contact point will reset automatically, recovering to normal working condition.
