BK1/MDA-12-R application field and working principle

Fuses are electrical components found in circuits that are designed to protect against high currents or short circuits. The BK1/MDA-12-R is a fuse primarily designed for general purpose applications, such as residential and commercial use. It is able to protect a circuit by providing quick breaking of an electrical connection when an excessive current flow is detected. This fuse works by having a certain amount of current passing through it to create a magnetic field, with a current passing through the active element of the fuse disrupting the magnetic field if the current is excessive.

The application field for the BK1/MDA-12-R fuse is mainly residential. It is typically used in fuse boxes that are smaller scale, such as consumer units, lighting boards and switchboards. It is also able to be utilized in switchgear, motor control centers and generators, providing a protective current limit on motor circuits and other circuits that handle large amounts of current. The BK1/MDA-12-R fuse is also compatible with appliances such as ovens, washers and dryers, but it is not suitable for use in outdoor applications.

The operation of the BK1/MDA-12-R is to detect an excessive current flow. When an excessive current is detected, the fuse will create an element with strong magnetic field that will quickly disrupt the power flow to the circuit, breaking the connection and effectively protecting the circuit. The main element of the BK1/MDA-12-R is a copper wire strip, a metal strip that continues to work when it encounters heat in an excessive flow of current. This wire strip is connected to a metal frame, with a fuse cartridge secured to the frame.

The BK1/MDA-12-R has a rating of 500VAC, with an amperage range of 0.5-45A. It is a one-pole fuse and it is UL listed and CSA-certified. It has a breaking capacity of 10kA at 500VAC and its main function is to offer overcurrent protection for electrical circuits and overloading protection for electrical equipment. The BK1/MDA-12-R also comes with a wide range of interchangeable accessories, such as mounting clips, indicator strips and clip kits, allowing for easy installation and connection.

In conclusion, the BK1/MDA-12-R is a one-pole fuse designed for general purpose applications. It is mainly used in switchgear, motor control centers and generators, as well as residential fuse boxes such as consumer units, lighting boards and switchboards. It has a rating of 500VAC, with an amperage range of 0.5-45A. It has a breaking capacity of 10kA at 500VAC and provides overcurrent and overload protection. The BK1/MDA-12-R comes with a range of interchangeable accessories for easy installation.
