0251005.MAT1L Circuit Protection

0251005.MAT1L Application Field and Working Principle

The 0251005.MAT1L is a type of fuse that has gained considerable popularity in recent years due its versatility and ability to cope with a variety of energizing and control applications. The fuse is rated for current values ranging from 2A up to 100A, and its customary European-style 5 x 20mm format means it is compatible with most in-system installation spaces. In particular, it is useful in power distribution circuits for protection against over-current events impacting the surrounding area, or for controlling energy management.

Application Field

The 0251005.MAT1L fuse has a wide application field in the industrial sector, including:

• Power and utility systems
• Control and communications systems
• Lighting and electrical systems
• Distributed power systems
• Earth leakage systems

The fuse has a good electrical protection characteristic where it is able to open the protected circuit instantly when it is unsustainably raised in voltage, current and/or temperature. This has made it popular for these application fields as it helps to minimize loss in the event of over-currents or other events.

Working Principle

The 0251005.MAT1L is a thermal-magnetic type fuse and has two operating principals: one that is thermally reactive, and the other that is magnetically reactive. This is combined to provide a fast current protection response with a re-setting during normal operation.

The thermally-reactive oprating principle works by detecting when the temperature of the fuse element has exceeded its predetermined limit. When this happens, the thermally-reactive element causes the fuse to open and the current to be cut. This is to reduce potential damage that could be caused by an over-current or other event.

The magnetically-reactive operating principle uses a coil wrapped around the fuse element. When the current flows through the element, the magnetic field created causes a flow of electrons around the coil. This creates an opposing force to the existing current and helps limit the current flowing through the fuse.

The two elements combine to provide a double layer of protection, and the fuse is able to open quickly in the event of an over-current or similar event and cut off the current. This helps protect the circuit and the surrounding areas from potential damage.

The 0251005.MAT1L fuse is a versatile and reliable option for a range of applications, providing quick response to over-currents and other events. It is well-suited for protection against electrical damage, and its wide application field has made it a popular choice for industrial and utility systems.
