Bottle fuse holders are designed to contain and secure bottle fuses, which are a type of circuit protection device that has end caps of a specific size, to ensure that the wrong fuse is never used. These allow the circuit to be completed.
How do bottle fuse holders work?
Bottle fuse holders form part of a circuit, providing a space for the connection of bottle fuses. The metal end caps of the bottle fuse connects to the metal contacts on the fuse holder, allowing current to flow through. When a fault such as a short circuit or overcurrent is detected, the fuse will blow, preventing damage to connected devices.
Types of bottle fuse holders
The key difference between different types of bottle fuse holders is their size. The end caps of bottle fuses have very specific different sizes, and therefore the fuse holders differ accordingly. They may also have different voltage and current ratings, numbers of poles, and mounting styles, being either surface or DIN rail.
