1) Triple-pole fuse base for bus-bar mounting
2) Rated voltage: 690V
3) Rated current: 400A
This series of fuses are mainly used in circuits of 50Hz AC, rated voltage up to 12kV and rated current up to 400A to protect the electric circuit from overloading and short-circuit. The breaking capacity of the high-voltage fuses is up to 40kA. The fuses comply with GB15166 and IEC291.282.644 and 787.

There are two kinds of connections for this series of high-voltage fuses. One is bus-bar connection. The fuse links are fastened to the bus bar directly with bolts. In this case the install volume is small and the connection is reliable. The other is insertion connection. The fuse links are inserted into the fuse seat. The fuse links replacement is convenient in this case.

The striker on the end face of the fuse links adopts a stored energy spring structure. Immediately at the appearance of the arc, the high-resistance nickel chrome wire paralleling to the fuse links melts, and the striker jumps out to push the chained equipment contact, signaling the melting or automatically cutting the circuit.
