125A NT00 Fuse Link

Description：

NT series square ceramic fuse is an electrical safety device used to protect circuits and equipment. It is usually made of ceramic material with a square shape and contains a metal wire or filament inside. When the current exceeds the rated value, the wire will fuse, cutting off the circuit and providing protection.

The 125A NT00 fuse link is designed to protect low-voltage distribution circuits by safely interrupting overcurrent and short-circuit faults.
