RT18-32X Series Solar PV DC Thermal Fuse 500V Fuse Holder
Product Description
Applications
This series of fuse links is mainly used in AC 50Hz, rated voltage up to 690V, rated current up to 125A and for protecting electric equipment from overload and short-circuit. It can reliably break the min. fusion current to any current wit-hin 120KA. It is also available for the protection of semiconductor parts and equipments against shortcircuit (type aR) and protection of motors (type aM). This series of fuse links conforms to GB13539 and IEC 60269 standards.
Design Features
Variable cross-section fuse element made from pure metal sealed in cartridge made from high-duty ceramic or epoxy glass.Fuse tube flled with chemically treated high-purity quartz sand as arc-extinguishing medium.Dot-welding of fuse element ends to the caps ensures raliable electric connection; Striker may be attached to the fuse link to provide immediate activation of micro-switch to give various signals or cut the circuit automa- tically. According to customer demands we can also produce speccial fuse body,this series of fuse-type plug-in structure, according to the size ,it can be installed in the RT14,RT18,RT19 and other corresponding size fuse assembly.
