Description
Square body fuses are a perfect solution for the applications that require a compact design and excellent reliability performance. Square body fuses have a variety of installation methods. There are two main installation methods for square fuses in Europe, one is the blade type and the other is the DIN type. These two installation methods are mainly derived from German standards.
Unlike the blade-type fuse that needs to be used with a matching base, Chifeng's American DIN type square body fuses are specially designed to mount the fuse with busbar directly. Chifeng provides optimal circuit protection for power semiconductor applications with DIN blade mounting and visual indicators.

FAQ
Q: For square fuses, can the standard indicator be mounted on different sides?
A: The standard visual indicator is on the end parts, and the double indicator type fuse can add a visual indicator on the ceramics body.
Q: What temperature should fuses be stored at?
A: Storage conditions should be in the -40°C to +85°C (-40°F to +185°F) range.
Q: What humidity is the fuse stored in?
A: Storage conditions should be no more than 70 percent relative humidity.
