ksd9700 thermal protector

Thermal protector is two different alloys together, through the current will generate heat, since two different alloys with different coefficients of thermal expansion, alloy bound to bend in one direction, the contact left, to cut off electricity. Bending speed proportional to the current passing through it. This protects the electrical equipment. Features: KSD9700 series is a double metal sheet as temperature sensing element thermostat. When the temperature dropped to a predetermined temperature is heavy contact automatically closed / open, return to normal working condition. Motors widely used in household appliances and electrical equipment, such as washing machine motor, air conditioner fan motors, transformers, ballasts, electric appliances. Installation Notes: 1. When using wire bending, it should be more than 6 mm from the root of parts bent; when folded, must not damage the roots and the lead can not be forced to pull, push, twist the leads. 2. Thermal fuse with screw, rivet or a post fixed manner, should be able to prevent millions of poor contact mechanical creep phenomenon. 3. Connecting member should be able to operate reliably within the operating range of electrical products, not because of vibration, shock and displaced. 4. When the wire bonding operation, heating and humidity should be limited to a minimum, notice shall be applied to high temperature in the hot links; do not forcibly pull, push, twist the thermal fuse and lead; After welding, should be cooled immediately more than 30 seconds. 5. Thermal fuse only at rated voltage, current and temperature conditions specified designated use, with particular attention to the maximum continuous thermal fuse can withstand temperatures. Note: nominal current, wire length and temperature according to customer's requirements for the design. KSD9700 thermal protection, small temperature switch, low-power motor coil temperature protection KSD9700 thermal protector is a heat conductive PBT housing or metal shell, bimetal component welded silver alloy contact, current conductive frame, insulation mounts, static touch pad and heat resistant wires and other components. Fully enclosed structure allows components from contamination by dust or impurities, to prevent damage to the penetration of liquid paint and external forces. Since the shell is a metal conductor, when using the configuration thermal conductivity and temperature insulating sleeve. Current through the bimetallic element impedance, the case of non-normal operation, if the current increases or the ambient temperature rises to the set temperature, the bimetallic element moves quickly, open the contact, cut off the circuit. When the device is cooled to a safe temperature, contact automatically closed, return to normal working condition. Widely used in single-phase, three-phase motors due to an overload, locked rotor caused by motor overheating protection under abnormal operating state, also applies to overheat protection and temperature control choke coil, spiral tubes and transformers and other electrical appliances in general.
