BK/S506-32-R

BK/S506-32-R Application Field and Working Principle

The BK/S506-32-R is a type of fuse designed for commercial and industrial applications. This fuse is a dual purpose, time delay fuse, which is used to protect a circuit against excess current and short-circuits. The BK/S506-32-R has a control rating of 32 amperes and a voltage rating of 250 volts AC.

Where is the Application Field?

The application field of the BK/S506-32-R fuse is typically used for general-purpose low-voltage and light-duty circuit protection. This fuse is typically used in light commercial and residential applications such as appliances, motors, compressors, air conditioners, refrigerators, freezers, and heating, ventilation, and air-conditioning systems. This fuse is also great for protecting branch circuits, lighting circuits, and plug-in circuits.

Working Principle

The BK/S506-32-R fuse is a time delay fuse with an “H” time delay rating. This type of fuse has two elements: the primary winding of wire and a secondary winding of wire. The primary winding carries a current which is controlled by a series of permanent magnets. When the current passing through the winding exceeds the rated current of the fuse, the magnets are drawn together and a second winding, the secondary winding, is activated. This current in the secondary winding then causes the fuse to trip and break the circuit.

This type of fuse also has self-resetting characteristics, which allow it to reset itself after a few seconds after the current is removed. This helps protect against nuisance tripping and helps reduce the number of nuisance trips.

Additional Considerations

When purchasing a fuse, it is important to consider additional features such as the voltage rating, current rating, and trip time. It is also important to select a fuse that is UL listed and rated for the application. The fuse should also be accompanied by application instructions, which can help to ensure proper installation and operation.
