BW9700 thermal protector KSD9700 thermal protection, temperature switches small, low-power motor coil temperature protection KSD9700 thermal protection by thermal PBT housing or metal shell, welded bimetal element silver alloy contacts, conductive frame, insulation mounts, static contact 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. Because the shell is a metal conductor, when using the configuration thermal conductivity and temperature of the 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 overload, stall caused by overheating of the motor under the protection of non-work state, also applies to overheat protection and temperature control choke coil, spiral tubes and transformers and other electrical appliances in general. First, the use of conditions 1, the relative humidity at -25 ℃ - + 125% 2, the atmospheric pressure: 86-106Kpa 3, Working Position: Any Second, the technical parameters 1, contact form: 1D or 1H 2, contact load: 220VAC 5A / 10A or 24VDC 5A / 10A 3, Insulation resistance: normal temperature and humidity ≥100MΩ 4, the contact resistance: ≤ 100 mΩ 5, dielectric strength: ≥1000VAC 6, vibration intensity: 50HZ single 0.35mm 7, impact strength: 150m / S2 8, Weight: <3g 9, life: ≥10,000 times three, four specifications data sheet, installation size and shape
