0FLQ.800HXR

Fuses are safety devices that play an important role in electrical circuits. 0FLQ.800HXR fuses are specially designed for medium-voltage circuits, and have the characteristics of fast action, high breaking capacity, and high breaking short-circuit current. These fuses are widely used to protect the power system from further damage due to short circuit or overload.

The 0FLQ.800HXR fuse follows the convention where the number following the letter “Q” indicates the voltage rating in hundreds of volts. The last two digits indicate the diameter in millimeters. Therefore, this specific fuse is rated for 800 volts and has a diameter of 8mm. The 0FLQ.800HXR fuse is a “constant-pressure” fuse, which is designed to open in a given time when the fault current exceeds a predetermined value.

The 0FLQ.800HXR fuse is a thermal-magnetic device, which means that the fuse has both thermal elements and magnetic elements. The thermal element is the main element of the fuse, and its purpose is to detect overloads and short circuits and open the circuit. The magnetic element allows a certain amount of overcurrent to pass through the device, which helps prevent the device from opening during a momentary overload or nuisance trip.

The fuse consists of a base and a capsule, which contains the thermal element and the magnetic element. The capsuler is made of a heat-sensitive material, such as lead, and is in contact with an independent trip circuit. The trip circuit is powered by a fixed current source. When the fault current rises above a predetermined value, the heat generated from the lead capsule causes the fuse to open.

The opening time of the 0FLQ.800HXR fuse is only 1 millisecond. During this short amount of time, the fuse opens the circuit and limits the fault current to a safe level. This prevents further damage to the power system and helps ensure the safety of personnel and equipment.

The 0FLQ.800HXR fuse is widely used in medium-voltage power distribution circuits and electronic equipment applications. It is designed for use on circuits up to 800 volts and can handle up to 100 amperes of current. The 0FLQ.800HR fuse is a cost-effective solution and provides a high level of safety and protection for medium-voltage applications.

In conclusion, the 0FLQ.800HXR fuse is a thermal-magnetic fuse designed for medium-voltage circuits. It is capable of fast action, high breaking capacity, and high breaking short-circuit current. Furthermore, it is economical and provides a high level of safety for medium-voltage applications.
