690V Flush End Square Body High Speed Fuse

Galaxy Fuse is a leading China 690V Flush End Square Body High Speed Fuse manufacturers. China fuse supplier Galaxy Fuse (Yinrong)’s YRSA3-PK square body high speed fuse provide maximum flexibility in equipment design and ultimate protection for today’s power conversion equipment. These square body fuses are available in two different operation classes gR and aR. YRSA3-PK gR fuse is designed for both overload and short-circuit protection. YRSA3-PK aR fuse is designed for short-circuit protection only. YRSA3-PK Square body high speed fuse is specially designed to protect semiconductor devices, provides a wide amperage rating of 500-2000A under the rated voltage of 690V/700VAC, which can fit most semiconductor devices. This YRSA3-PK Square body high speed fuse conformed to the nation standard GB13539.4 and the international electrical committee standard IEC60269-4. This square series of fuses for semiconductor equipment protection has low I²t value, high current limiting capability and high breaking capability. Many square body fuses are equipped with a trip-indicator. This trip indicator can operate a field-mountable micro switch which is easily mounted directly to busbar. Galaxy Fuse (Yinrong) also affords various high speed fuses to meet global requirements.
