Electrical systems are used in many different applications across many types of industries, from commercial and industrial electrical systems to individual consumer appliances. In order to ensure proper functioning and safety, most electrical systems require components such as fuses, which are designed to protect circuits and other electrical components from dangerous levels of current or voltage. The 0FLQ004.T is an example of a specialty fuse designed specifically for higher levels of current or voltage protection.

0FLQ004.T Application Field:

The 0FLQ004.T is a high-voltage-short-time fuse, designed for protection of AC circuits with high fault currents, such as motors, cables, transformers and power electronics. Typical applications include AC circuit protection in power generating plants, substations, petrochemical plants, and industrial control systems. It is suitable for branch circuit protection of motors with multiple loads, as well as for power electronics in manufacturing, control and process automation. The 0FLQ004.T is available in AC and DC voltage ratings from 250V up to 6,900V.

0FLQ004.T Working Principle:

The 0FLQ004.T fuse operates on the principle of thermal-magnetic protection. The fuse consists of a metallic element that is heated when current flows through it. If the current is too high for too long, the element will become so hot that it melts, thus breaking the circuit and protecting it from further damage. At the same time, a bimetallic strip in the fuse senses the temperature increase due to the high current and triggers a magnetic release, which acts to open the circuit and stop the current through the fuse. This dual thermal-magnetic protection ensures that the fuse can quickly and reliably protect any circuit from excess current.

The 0FLQ004.T also features a wide range of protection features, such as current limitation, overload protection, short-circuit protection, and high-temperature operation. The fuse can also provide protection against voltage surges, arc-faults, and open-circuit conditions. Additionally, it has an internal LED indicator to show when the fuse has opened due to an overcurrent. This LED indicator can be used to quickly identify the cause of a fault and repair any related damaged components.

The 0FLQ004.T fuse is UL and CSA listed and provides excellent performance and reliability, making it suitable for a variety of specialized applications. Its wide range of ratings, performance features, and reliable protection make it a great choice for AC and DC circuit protection applications.
