Audited Supplier
Model No: LYB103
Introduce:
1.name: fixed contact.
2.rated current:400A, 630A, 1000A, 1250A, 1600A,2000A, 3150A, 4000A.
3.contact material: T2 red copper.
4.surface treatment: thick silver-plated, discoloring proof treatment.
Features:
1.Copper and aluminum combine products are new generations product.
2.The tensile and bending strength of it are outstanding, and bonding performance is also good.
3.There are no surface cracks after flattening and bending, they are the domestic new tpe of enery saving products currently.
4.Dynamic thermal stability, temperature rise and loop resistance are all compare favorably with the same levels of T2 copper, this is the idea products of the present electrical industry which can lower the costs.
Experimental measurement and test:
