Product Description

YRSA01/1/2/3-H(K) 1250V 40-2000A High-Speed Fuses are designed for both overload and short-circuit protection. YRSA(x)-HK Series gR high speed fuses provide a wide amperage rating of 40-2000A under the rated voltage of 1250V (IEC/UL), which can typically fit most semiconductor devices. This YRSA(x)-HK Series gR high speed fuse conforms to the national standard GB13539.4 and the international electrical committee standard IEC60269-4.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 onto the fuse. Galaxy Fuse (Yinrong) also affords various high speed fuses to meet customers' requirements.
