Galaxy Fuse is a leading China 690V 630A YRSA1-PK High Speed Fuse manufacturers. China high speed semiconductor fuse manufacturer Galaxy Fuse (Yinrong)’s YRSA1-PK gR high speed fuse is specially designed to protect semiconductor devices. YRSA1-PK gR high speed fuse is designed for both overload and short-circuit protection. YRSA1-PK gR high speed fuse provides a wide amperage rating of 200-630A under the rated voltage of 690V/700VAC (IEC/UL), which can typically fit most semiconductor devices. This YRSA1-PK gR high speed fuse conformed to the nation standard GB13539.4 and the international electrical committee standard IEC60269-4. Besides, it also can be used for short circuit for electric vehicle drive power systems, power conversion systems, energy storage and power batteries, energy storage capacitors, inverter controllers, chargers, wires, automotive devices and other backup protection.
