FLSR07.5T

Fusible link short-circuit releasing (FLSR) device is a type of device used in power system for short-circuit protection. The most common type used is the FLSR07.5T, which is a fuse designed for current limiting applications. This device provides quick-acting short-circuit protection for power systems. In this article, we will discuss the application field and working principle of the FLSR07.5T.

The most common application field of the FLSR07.5T is in medium and high voltage circuit breaker. This device can be used for short-circuit protection in control circuits, power lines, auxiliary lines, transformers, and other systems related to electrical equipment. In some cases, the device can be used as an auxiliary switch to provide the main switch with the ability to manually isolate a circuit. The FLSR07.5T is widely used in the power industry, especially in the distribution, transmission, and substation sectors.

The FLSR07.5T device is designed to limit the current through a circuit if overload occurs. This device will open the circuit in a short amount of time when an overload, short-circuit, or other fault is detected. The device is designed to act as an electric switch, which is capable of quickly cutting off the current in the circuit in order to prevent catastrophic damage due to faulty electrical systems. The device will open the circuit if the current exceeds a certain threshold and can reset automatically.

The FLSR07.5T can also be used as a circuit breaker. It is designed to provide instantaneous current interruption when an overload, short-circuit, or other fault condition is detected. It is typically used in AC systems, as it is capable of dealing with both AC and DC current. It can also be used in both industrial and residential installations.

The working principle of the FLSR07.5T is based on a mechanical action that causes the contact blades to pivot and separated. When there is an overload, short-circuit, or other fault condition, the blades will separate and move to the “open” position, breaking the connection between the circuit and the power supply. This will prevent further damage to the electrical system as the circuit is interrupted. The device will reset automatically after the fault has cleared.

In conclusion, the FLSR07.5T is a specialized fuse designed mainly for current limiting applications. It is designed to provide quick-acting short-circuit protection for power systems. The most common application of this device is in medium and high voltage circuit breaker. The working principle of the FLSR07.5T is based on a mechanical action that causes the contact blades to pivot and separated when an overload, short-circuit, or other fault condition is detected.
