Product Description
The Current limited Back Fuse (Cl fuse)is used in transformers to protect and isolate faulted equipment. Whenconnected in series with a low current primary protection device, such as Bay-0-Net fuse link, the Cl fuse becomesan element of a two part protection system that gives a full range of fault protection.This two-part system provides low current protection with the replaceable expulsion fuse . Together,the Cl fusecoordinate easily with upstream and downstream devices.
This product applies to indoor AC 50~60Hz system with the rated voltage of 8.3 ~ 40.5kV for the short-circuit protection of transformer and other power equipment, and is used in series with the oil-immersed transformer overload protection fuse (Bay-O-net Fuse), and can provide the full range protection for indoor power system. The product has passed the type test conducted by the national high-voltage electrical equipment quality supervision and inspection center, and conforms to GB15166.2, IEC282-1 and IEEE C57.92.
