Covered Fuseholders


Over this past weekend, headlines read of blizzard conditions along the eastern seaboard.  The snow closed many of the transportation hubs from Washington DC to Boston.  People stayed home instead of going out to complete last-minute holiday shopping.

This got me thinking about the harsh environmental conditions that our vehicles must endure each day to keep operating.

OptiFuse sells a lot of fuse holders for transportation applications (in fact in reality...we sell a lot more fuseholders than we do fuses).  Almost all inline fuse holders are available with or without covers...

The cover helps the fuses stay dry during wet or humid weather conditions.  The covers also help to protect the fuses from dust and other airborne particles.  The cover also helps to protect the fuses and fuse contacts from corrosion from salt air environments (or salt placed on the highway during holiday snow storms)

The additional cost of a fuseholder with a cover is only a few cents higher than that of one without a cover, but for a few cents does it really make sense not to have the added insurance? 

Fuseholders with a cover are typically rated to an IP-64 rating which protects the fuse against water splash and all particles.

OptiFuse manufacturers fuseholders with a cover for mini, regular and maxi type automotive fuses as well as a splash-proof holder for standard 3AG (¼" x 1 ¼") type fuses

A disclaimer needs to be made at this point letting you know that these fuseholders are considered "splash-proof" only as opposed to "water-proof".  These fuseholders are not intended for submersible applications.

OptiFuse will close this Wednesday, December 23rd at 12 noon for the Christmas holiday and reopen on Monday December 28th. 

Thank you very much for supporting OptiFuse where you’ll find that protection comes in many different forms.
