The PRW10 and PRHW10 series outdoor high-voltage drop out fuses are suitable for outdoor overhead distribution systems with AC 50Hz and rated voltage of 10kV~35kV. They are used as overload and short circuit protection for lines or power transformers. Some products also have the function of combining and dividing load currents. After normal operation or handling, the load fuse drops, forming a visible fracture, which plays a safety guarantee role in maintenance and repair

PRW10 and PRHW10 series outdoor high-voltage drop out fuses under normal operating conditions

a) The ambient temperature shall not exceed+40 ℃ and shall not be lower than -40 ℃;
b) Wind pressure not exceeding 70OPa (equivalent to a wind speed of 34m/s)
c) Altitude not exceeding 1000m;
d) A place without serious pollution, chemical corrosion, flammability, explosiveness, and severe vibration.

Product Features
The product adopts a single end exhaust structure, which can ensure reliable disconnection of fault current from overload to short circuit, and prevent damage to the circuit or equipment above the fuse installation site during the disconnection process.
The upper contact seat applies positive pressure to the upper contact of the load fuse, effectively ensuring good conductive contact and reliable drop of the load fuse after disconnection.
The special wiring terminal structure can easily fix various wires, and a wrench can be used to complete the wiring operation with one hand.
The specially designed fork hook can effectively guide the molten material into the closing position, and also provides the possibility of using portable load cutters.
