BK/TEL-350MA

Fuses are adopted in various electrical circuits for overload and short-circuit protection. BK/TEL-350MA is a type of fuse that is widely used in commercial and industrial applications. This paper will discuss the application fields of BK/TEL-350MA, and its working principle.

Application Field of BK/TEL-350MA

BK/TEL-350MA is a BS 88 type fuse, available in ratings of 20A, 32A, 40A, and 63A. It has a breaking capacity of up to 100kA. It is suitable for AC circuits up to 440V, systems operating at frequencies of 50 Hz to 400 Hz. The fuse is designed for protection of semiconductors including thyristors, FETs, triacs, and power transistors.

BK/TEL-350MA can be used in a variety of industrial applications including motor circuits, lighting circuits, UPS systems, AC drives, electric motors, variable speed controllers, transformers and other circuit protection devices. It is also widely used in residential AC systems, such as heating systems, air conditioning systems, and refrigeration systems. The fuse can also be used in automotive applications such as power seats, sunroofs, and other electrical components.

Working Principle of BK/TEL-350MA

The BK/TEL-350MA is a current-limiting fuse, which means it is designed to quickly reduce the amount of current to a safe level when an electrical fault occurs. It is designed with a fuse element that is embedded in a hard ceramic insulator. The fuse element is a thin strip of metal which is melted by the current when an overload occurs, which causes the fuse to break the circuit in a fraction of a second.

The BK/TEL-350MA is designed with a special metallurgical composition which ensures that it melts very quickly when the rated current is exceeded. This helps to ensure that the fuse can limit the current and prevent damage to the system. The fuse can also handle a short-circuit, as it is able to withstand very high temperatures without melting.

The fuse is also designed to be resistant to abuse, vibration, moisture, and other extreme environmental conditions. The fuse can withstand shocks and vibrations up to 1000G. It is also dust-proof and water-resistant, making it suitable for use in various types of industrial applications.

The BK/TEL-350MA is a highly versatile fuse, which can be used in a variety of different applications. It is designed to provide reliable protection against overloads and short-circuits, making it an ideal choice for industrial, commercial, and residential applications.
