Fuses: MS 4TR application field and working principle

Fuses are essential safety products and play an important role in various areas. The application fields of Fuses mainly include the following four areas.

1. Household Field

As the common Home Appliances, such as water heater, refrigerator, air conditioner, washing machine and so on, which can\'t work without a Fuse. A properly sized and rated Fuse is inserted into the circuit to protect it from overheating and overcurrent. These Fuses are installed in the connection between the power distribution and the equipment, as well as between the equipment and the equipment in the power transmission line.

2. Industrial Field

In industrial fields, Fuses are widely used in the wiring circuit of large and medium-sized production equipment, such as motor, lathe, machine tool and precision small electrical appliance machine. In this case, a fuse rating is needed to determine the consistent working current. Fuses can protect the circuit from overloading and short circuit.

3. Automotive Field

Fuses are also widely used in the wiring of the automotive circuit. As we all know, the power of an automobile is large and the current demand is strong, so the fuse used is usually a high voltage fuse. Generally speaking, the fuse installed in the car is also an abnormal overload protection device, which can effectively protect the wiring circuit of the whole car from overloading and short circuit.

4. MS 4TR application field

MS 4TR is a kind of fuse that can realize remote control, protection and coordination functions. MS 4TR provides protection functions such as overcurrent, overvoltage and short circuit protection. It can widely be used in telecommunication equipment, AC power supply system, household equipment, electrical distribution network, automotive circuit and other fields.

Working Principle

The MS 4TR fuse has a built-in temperature sensitive detection element, which can detect the operating temperature of the fuse junction point, and then transmit the detected temperature information to the control unit. The control unit then analyzes the temperature information collected and identifies it as a normal electrical event or an electrical failure. If the temperature of the fuse junction exceeds the set temperature, it will start the protection function, and the current shall be cut off quickly. In addition, the MS 4TR fuse has two kinds of input signal mode, one is self-contained input signal input, the other is external signal input. Self-contained signal input means that the fuse will act according to the set value, and external signal input means that, the fuse can detect the external temperature and current changes through the installed sensor, and then analyze and judge whether to act according to the data obtained. It can protect the equipment from overload, short circuit, lightning and other factors.To sum up, the working principle of MS 4TR fuse is mainly based on its temperature-sensitive detection elements. The fuse uses the temperature-sensitive detection element to detect the temperature change of the fuse junction, and then transmits the obtained temperature data to the control unit to judge whether the fuse shall be disconnected or not. Therefore, the protection of this kind of fuse is more stable and reliable.
