MDA-2/10-R

Fuses are used to protect electrical equipment and components from overload, short-circuiting and overvoltage conditions. The MDA-2/10-R is a type of fuse composed of a container and a pre-filled resistor element, which offers over-voltage protection and satisfies the requirements of circuit protection devices. This fuse allows for the compensation of different system voltages.

The MDA-2/10-R fuse works in two parts. The first part is the container, which provides the mounting structure for the integrated discrete resistor element that sits within. This container is made up of a ceramic material with a glass-melted surface. It can also resist extreme temperature conditions ranging from –40º C up to +105º C. A thin layer of high-temperature fluorine ethylene resin is applied on the surface to provide dielectric insulation. The second part of the fuse is the resistor element which is composed of two thick-film resistors which are pre-filled in the container.

The MDA-2/10-R fuse operates as a low ohmic resistor during normal use and prevents over-voltage situations. This fuse has a low open circuit voltage that ranges from 50V to 1000V and 20mΩ to 200mΩ. When an over-voltage occurs, the resistor element goes through two metallizations to break the current flow and to open the circuit. In addition, this fuse has a high chopping process or blow-out process which can safely dismantle the circuit before it causes any damage.

The MDA-2/10-R fuse has various applications in industrial, domestic and commercial areas. It can be used in lighting systems, uninterruptible power supplies (UPS), motor protection systems, lighting systems, emergency systems, automotive, and railway systems. In some areas, due to its unique features, it can also be used in low power circuits and in fields that require long over-voltage protection. It is also an ideal choice for sensitive electrical components, such as solid-state switchgear and load break switches, due to its low power dissipation abilities. Furthermore, this fuse can help reduce the power loss at the operating voltage compared to other types of fuses.

In summary, the MDA-2/10-R is a type of fuse that offers over-voltage protection and prevents the electrical equipment and components from damage due to the overload, short-circuiting, and overvoltage conditions. It provides high chopping process or blow-out process that can safely dismantle the circuit before it causes any damage. This fuse is also suitable for use in various industrial, domestic, and commercial areas, and it can help reduce the power loss at the operating voltage compared to other types of fuses.
