Fast Blow Fuse Curve

Type cls high voltage power fuses.

Fast blow fuse curve.

The use of power semiconductor devices in modern power electronics is driven by the need for better power efficiency with the ultimate goal of achieving as close to 100 power efficiency as possible. Choose from our selection of slow blow fuses including time delay glass tube fuses time delay ceramic tube fuses and more. But a slow blow one will melt its fuse wire after a specific period within 10 or 15 seconds. If a circuit has a fast acting fuse it means the circuit does not tolerate any high transient current changes and needs to be immediately disconnected.

Very fast acting fast acting or slo blo fuse. Selecting a fast blow fuse is fairly straightforward. In stock and ready to ship. There are various types of fuses.

Cle hle and hcl fuses time current curves. If you are a beginner or you don t have any experience whatsoever in electrical work then you have to learn to distinguish among different types of fuses. 25 and 38 kv type clpt current limiting fuse trip curve. For example if you send 40 amp current through a 30 amp fast blow fuse it will blow almost immediately.

Clpt and nclpt fuses time current curves. Note that a 1 a fuse will blow after 10 000 seconds with exactly 1 a applied. Clt fuses time current curves. E rated medium voltage for transformers and.

Many people think that time delay fuses are less effective because they allow current overloads pass through the circuits. 8 15 kv type clpt current limiting fuse trip curve. The time current curve describes how fast a fuse will blow at any given current. The distinguishing feature of slo blo fuses is that these fuses have additional thermal inertia.

Fuse characteristics can be classified into three general categories. For example assume a nominal load of 15 amps and an ambient temperature of 105 c. A power semiconductor device is a high power electronic device that is used as a switch for control and conversion in electric power. Thus changing a fast acting fuse with a slow blow fuse will be vulnerable as the circuit will not become immune to the high transient changes and could lead to a total failure in those situations.

It has a log log scale. This characteristic of a fuse design refers to how rapidly it responds to various current overloads.
