Fuse Holder and Fuse Carrier
A fuse holder is mounted in the equipment and is designed to hold the fuse. Fuse holders can hold both North American and international sized fuses. This is based on which fuse carrier is being used. Interpower offers panel-mount fuse holders.
International “touchproof” fuse holders are a popular choice. This type of fuse holder is available in low-profile, high-profile, and low-profile/snap-in versions. Each of these are available with a variety of terminal styles including quick disconnect, solder/quick disconnect and angled versions of both. Interpower fuse holders will also accept both North American and the international fuse carrier and can be used in nearly every market worldwide. These fuse holders offer the additional benefit of being touchproof, providing more safety to the end user—the blown fuse can only be accessed from the outside of the equipment with the use of a tool and cannot touch any of the contact surfaces before the fuse carrier and fuse is removed.
A fuse carrier is the “cap” to the fuse holder. It carries the fuse into the holder and secures the fuse in place. One of the benefits of using a fuse carrier in conjunction with a fuse holder is that they are touchproof.
Fuse Clip
A fuse clip is for internal fuses on PC boards. It takes two of the clips for one fuse.
Fuse clips are an alternative to fuse blocks, with many of the same features. Interpower fuse clips come in one size. They are PC-board mounted and accessible only from within the equipment. It has a “stop” on it, to help position the fuse when it is being inserted. No approvals are available on fuse clips, except as part of the finished product. Because they are inexpensive, they are another attractive alternative to post style and PC-board mount fuse holders. If fuse clips are used, the designer must remember that each end is a separate piece. Two clips will need to be ordered for each fuse used.
