A fuse holder is a housing enclosure, mounted in the equipment and is designed to hold the fuse. A fuse that is simple to remove or easy to install indicates shorter downtime and safer replacement leading to cost-cutting. Fuse Holders are used for Power Supplies, Stabilizers, UPS, Solar Lanterns, Water Purifiers, Power Controllers, Bedside Monitor, Defibrillators, E-bikes. Fuse holders can hold both North American and international sized fuses. Elcom offers a wide range of fuse holders and variants to handle circuit protection, as per the industry requirement, with the flexibility to incorporate fuse holders into a circuit in various ways. A suitable pairing of fuse and fuse holder is ensured at design stage itself. The major design considerations include:
