NEC SF SEFUSE Axial Lead No Resettable 10A 15A 250V Metal Temperature Cutoff Motor Thermal Fuse

SEFUSE (temperature overheating fuse) has a small and strong temperature overheating fuse that detects abnormal temperature and cuts off the circuit. It can detect the abnormal temperature rise of household or industrial electrical products and cut off the circuit quickly and timely, which can achieve the effect of preventing fires in the first place.

SEFUSE has two types: SF type using heat sensitive particles (organic chemical substances) as heat-sensitive material and SM type using low melting point alloy. Rated operating temperature range: SF type is 73°C~240°C, SM type is 76°C~187°C. There are various products with rated current of 0.5A~15A. SEFUSE is manufactured in a factory that has passed the quality assurance standard <IS09001> of the International Organization for Standardization (ISO).

SF Type Thermal Fuse

The SF type is a temperature overheating fuse that uses metal as the outer shell and heat-sensitive particles (organic chemical substances) as the heat-sensitive body. Since the structure of the heat-sensitive material is not energized, the internal impedance is small and the cut-off current (rated current) is as large as 6A~15A (AC)

SM Type Thermal Fuse

The SM type is a temperature overheating fuse that uses ceramics as the shell and low-melting alloy (melt) as the heat-sensitive body. Its cut-off current (rated current) is 0.5A~2.0A (AC). Because the outer shell is an insulator, the ceramic has the feature that it can be installed close to the temperature detection side.
