Механические термовыключатели Устройства (Серия DF SF 10 А)

SF DF Series thermal cutoff assembly and equipment. The thermal cutoff assembly includes: a thermal cutoff connected to a DC circuit. The thermal cutoff is connected in parallel with a capacitor or a capacitor loop, which is formed by a plurality of capacitors connected in series. The capacitance of the capacitor or the total capacitance of the capacitor loop satisfies the following conditions: at the moment when the thermal cutoff is disconnected, the DC circuit charges a capacitor or a capacitor loop. Впоследствии, напряжение между контактами термовыключателя и цепью постоянного тока повышается, обеспечивая размыкание цепи постоянного тока. Благодаря настоящему изобретению, решена проблема, заключающаяся в том, что термовыключатель в цепи постоянного тока не может эффективно отключить цепь, и достигается эффект повышения безопасности цепи.

Диапазон рабочих температур:
SF type is 73 ℃ ~ 240 ℃, SM type is 76 ℃ ~ 187 ℃. There are various products with a rated current of 0.5A to 15A. Safety certifications include: UL, CSA, ВДЕ, BEBA, PSE, JET, ККК … certificates. Comply with EU ROHS environmental protection directive requirements. NEC temperature fuse has the function of detecting abnormal temperature and cutting off the circuit. It can detect abnormal temperature rises of household or industrial electrical products and quickly and timely cut off the circuit, which can prevent the fire from being unburned.
NEC thermal fuse is a component that provides very reliable protection in over-temperature conditions. It has small volume, large overcurrent, non-reset, stable performance, convenient installation, and has a range of humidity settings and carrying capacity to choose from to meet customer application requirements.
Products are widely used in:
Various motors, copiers, fax machines, HID ballasts, fluorescent lighting ballasts, трансформаторы, chargers, battery packs, heating appliances, электрические утюги, hot air blowers, электрические плиты, рисоварки, электрические чайники, coffee makers, Ventilation fans, electric fans, electric sewing machines, water heaters, power converters, power plug sockets, холодильники, кондиционеры, automotive air conditioners, meters, equipment, и т. д.. are over-temperature protected.
