Mechanical resistance thermal cutoffs Devices (DF SF Series 10amp)

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. Subsequently, the voltage between the contacts of the thermal cutoff and the DC circuit rises to ensure that the DC circuit is disconnected. Through the present invention, the problem that the thermal cutoff in the DC circuit cannot effectively cut off the circuit is solved, and the effect of improving the circuit safety is achieved.

工作溫度範圍:
SF type is 73 °C ~ 240 攝氏度, SM type is 76 °C ~ 187 攝氏度. There are various products with a rated current of 0.5A to 15A. Safety certifications include: UL認證, CSA （英語：CSA）, VDE, BEBA, PSE, JET, CQC質素控制 … 證書. 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.
