FWX-80A is a special type of fuse designed to quickly protect circuits against overloads and short circuit events. It is a resettable fuse that has a small metal element replaces the traditional blown wire-fiber element. This miniature component resists higher amperage and can sense a current increase faster than typical blade type fuses, making it an excellent choice for higher power circuits. The use of a FWX-80A can greatly reduce cost and maintenance when compared to more traditional fuses.

The FWX-80A is a Time-Lag fuse that reacts to current surges. When a fault in the system causes a current overload greater than the rating of the fuse, the thin metal element melts, disconnecting the circuit and preventing any further increase in current. Once the fault is cleared, the thermal element re-connects, allowing the circuit to resume operation. It is this repeatable thermal functionality that differentiates the FWX-80A from other time-lag fuses.

The FWX-80A is rated for up to 80A at 250VAC/DC. It can be used in a wide variety of applications such as residential, industrial, automotive, HVAC, motors and solar. Its slim design makes for an easy installation and can be used in tight spaces. It also offers superior current-sensing capability with minimal over/under voltage ratings.

In terms of working principle, the FWX-80A operates on the principle of thermal conduction. The fuse comprises of an internal contact and a thermal element, which in turn are connected to an outer shell. The current flowing through the element is converted to heat, which then is distributed evenly throughout the thermal element. When the accumulated heat is greater than the current that is passing through the fuse, the element will melt and disconnect the contacts, breaking the circuit in the process. The thermal element then cools down, allowing the current to flow again. This process allows the FWX-80A fuse to operate on an ongoing cycle, which makes it an ideal choice for protecting circuits from overload.

The FWX-80A can also be used as a backup protective device in more critical circuits. It is one of the most reliable fuses and is known for its high accuracy, fast response time and excellent surge protection capabilities. It can be used in a variety of applications and it is a must for any circuit where protection against current overloads is required.
