What is a 3 phase fuse carrier?
3 Phase Fuse Carrier is the medium that can carry fuse.There are a lot of fuse carrier box.
The carriers vary from outlook,structure,installation,test standard,function,material,quality,brand and so on.Below passage only covered information for fuse carrier in low voltage.
The material of the 3 phase fuse carrier ？
DNF1 consists of base,contact,cover and other components.The 3 Phase Fuse Carrier is made of PA66, flame retardant V0 level.Contact is made of T2 copper with tin plated.DNF2 is in same structure with DNF1,but the base material is made of ceramic.By the way,GRL also can do customized products,for example,the base material also can be steel plate for better performance.
How to choose 3 phase fuse carrier?
3 Phase Fuse Carrier varies from performance,sizes and qualities.
Following 5 steps can help you choose the right fuse carrier box.
Step 1.Make sure what kind of fuse carrier is needed.There are many choice,such as fuse carrier for NH knife fuse,fuse carrier for wedge type fuse,fuse carrier for bolt type fuse, fuse holder for cylindrical fuse and so on.
Step 2. What ampere and voltage is the fuse carrier to bear.Generally speaking,Fuse carrier size should match with fuse size.Maximum current of NH00 fuse is 160 A,maximum current of NH1 fuse is 250 A.Maximum current of NH2 fuse is 400 A.Maximum current of NH3 fuse is 630 A.
For cylindrical fuse,maximum current of 10×38 fuse is 32 A.Maximum current of 14×51 fuse is 63 A.Maximum current of 22×58 fuse is 125 A.Then we need to consider the voltage.You can check the voltage with supplier if they can meet.
Step 3. Match the size of fuse and fuse carrier.Fuse carrier size is generally same with fuse size.
Step 4. Pole No. You might need 1P,2P,3P or with N Pole.Just state it clearly.
Step 5. If there is any other special requirement.Such as material,other special performance requirement,etc..
Test Report and Certificates of 3 phase fuse carrier
