Electric 200 Amp 200a Cut Out Fuse

An electric 200 amp 200a cut out fuse is made up of three main components: an insulating support, a set of fixed and moving contacts, and a fuse tube. The fixed contacts are mounted at both ends of the insulator, while the fuse tube consists of an inner arc extinguishing tube and an outer protective tube made of phenolic paper or epoxy glass fiber.

The electric 200 amp 200a cut out fuse is designed for apply in power systems with a frequency of 50 Hz and a rated voltage up to 35 kV. It is commonly installed on the medium voltage side of distribution transformers or on distribution feeder lines.

In applications where protection requirements are moderate, the electric 200 amp 200a cut out fuse can be worked together with an isolating switch which is an excellent replacement to an automatic air circuit breaker. It can also be combined with a load break switch as a cost effective alternative to a circuit breaker. On the power circuit, the electric 200 amp 200a cut out fuse provides short circuit and overload protection, while offering a visible isolation for maintenance safety.

Product FAQ:

1. Q: What type of fuse link should be used on an electric 200 amp 200a cut out fuse?

A: it is recommended to use 200 A standard expulsion type fuse links rated. Fuse links shall be coordinated with upstream and downstream protection devices to ensure proper system protection.

2. Q: How should an electric 200 amp 200a cut out fuse be installed?

A: The an electric 200 amp 200a cut out fuse should be mounted vertically on a pole or cross arm. Line and load terminals must be connected correctly to ensure proper drop out operation. Adequate clearances should be maintained according to local safety codes.

3. Q: What is the expected service life of an electric 200 amp 200a cut out fuse?

A: Under normal operating conditions, the mechanical and electrical life exceeds 20 years. Environmental factors, load cycles, and the number of fault operations can affect longevity.
