What is a size rejecting fuse?
What is a size rejecting fuse?
The rejection feature prevents a fuse with a larger current rating from being substituted for the fuse of a smaller size that was originally specified. …
What is a rejection type fuse?
A rejection feature is used to prevent fuses with a lower voltage or interrupting rating (such as Class H and Midget fuses) from being used in a circuit that needs a higher rating.
What kind of fuse holder do I need for my car?
Automotive and Commercial Vehicle Fuse Holders. Fuseholders for automotive style fuses including MINI, ATO, MAXI, MIDI, MEGA, JCASE and Universal Glass Fuses. Fuseholders are available for In-Line, Bolt-Down, Panel Mount and PCB applications.

Which is the best fuse for high voltage?
Littelfuse manufactures the broadest and most innovative selection of fuses. Provide a complete, one-piece solution for easy procurement and code compliance. Dissipate high voltage transients through a contained plasma gas with high surge capability, low capacitance and small size.
Can a panel-mounted fuse holder be derated?
In the case of panel-mounted fuse-holders it may be safer to derate even further due to their enclosed nature and the tendency to use push-on connectors which also have a contributory contact resistance. A fuse link in a panel-mounted fuse-holder should be downrated by 5 or 10%, due to the poorer heat transfer properties in this arrangement.
What should the voltage of a fuse holder be?
A fuse link in a panel-mounted fuse-holder should be downrated by 5 or 10%, due to the poorer heat transfer properties in this arrangement. The voltage rating of a fuse-holder is governed by a number of design aspects like the distance between terminals, creepage distances and minimum clearance distances.
What’s the difference between a fuse holder and a block?
In the following, some of the most important differences between the two standards will be indicated. From an application point of view, a fuse-holder is characterized by the features discussed in the previous section by its rated values for voltage, current, and accepted power.
What is the rated power of a Littelfuse fuse?
Rated values of accepted power are 1.6 W, 2.5 W or 4 W. For example, it means that at a power dissipation of 4 W (by a fuse link placed in the fuseholder) temperatures of the fuse-holder should not exceed certain limit values as specified in the standard. This rated accepted power determines the rated current.
