Xiamen SET (SETfuse) Electronics Co. Ltd. is engaged in designing and manufacturing circuit protection components and providing integrated circuit protection solutions. With 15 years of innovative history, we have obtained lots of patents.

SETfuse developed unique PATENTED advanced MOV with Alloy Thermal Fuse(TFMOV). This technology can effectively avoid hidden FIRE RISK caused by common MOV. There are many extended products from TFMOV, such as TFMOV21R3P series which integrated 3 MOVs and 2 Thermal Fuses to proceed all-mode protection(L-N, L-G, N-G), combo of TFMOV and GDT for telecom power and PV power and LED roadway lighting. SETfuse also developed another PATENTED product based on Thermally Protected Fusing Resistor with built-in TCO(TRXF), this technology can effectively solve the hidden burning problem caused by SMALL FAULT CURRENT in the circuit of phone charger or LED lamp.

Our products are component-recognized in China as well as internationally by several organizations. Several Fortune Global 500 companies are using our products.
