FLNR500.XXID

In industrial settings, it is important to ensure that electrical circuits and components are protected from electrical damage. In order to do this, special components such as speciality fuses are often used. The FLNR500.XXID application field and working principle are one of the many speciality fuses that can provide protection for a range of applications.

The FLNR500.XXID is a two-pole fuse which is designed to protect against short circuits, overloads and other types of fault currents. It has a high current rating of 500A, making it suitable for use in industrial settings, and is UL recognized and compliant. The fuse is made from a modified version of a standard metal oxide varistor (MOV) which provides superior protection against surge currents, making it ideal for high voltage applications such as solar and wind power installations.

The fuse operates on the principle of thermal-magnetic protection. When a current flows through the fuse, a resistor element heats up and triggers a magnetic trip, which will open the circuit and break the flow of current. The trip current is determined by the temperature of the resistor element; the warmer it gets, the greater the trip current will be. This makes it ideal for applications where surges in power levels may occur, such as electrical substations, as it can provide an effective level of protection from damage.

The FLNR500.XXID also features a quick-opening mechanism which helps to ensure that the fuse opens instantly when required. This allows the circuit to be protected quickly and efficiently, without having to wait for the thermal-magnetic trip current to occur.

In addition to providing protection from fault currents, the FLNR500.XXID also features a range of pre-insertion contacts which allow it to be installed quickly and easily. The fuse can be easily locked in place using threaded retention screws, making it ideal for use in applications where access to the fuse is limited or difficult.

The FLNR500.XXID is a versatile and effective electrical fuse that can provide reliable protection against short circuits and overloads. It is an ideal choice for a variety of applications and can provide an effective level of protection against surge currents. The quick-opening mechanism ensures that circuits can be protected quickly and easily, and the range of pre-insertion contacts make it easy to install the fuse.
