2570103

Fuseholders are a vital component in the safe operation of most electrical systems, and the 2570103 series of holders is no different. The holder uses a proven plunger-type design, allowing it to accept standard size fuses. In addition, the holder is designed to prevent accidental release of the fuse or shorting of the contacts during use. The design also allows for tool-less maintenance, making replacement of the fuse extremely fast and easy.

The 2570103 fuseholders are designed for use in all types of electrical systems from low voltage residential, commercial to medium-high voltage switch gear and generator applications. These holders are also suitable for industrial installations where safety protocols are of utmost importance. The holders are UL listed and meet the requirements of the National Electrical Code.

In order to use the holder, the fuse must be inserted into its respective slot. The plunger-type holder is then activated by latching into the fuse. Once the fuse is lodged within the holder, it becomes an integral part of the system. This makes it possible to achieve superior electrical continuity between the fuse and the system. The power distribution system is then ready to deliver the power it was designed to.

The majority of the designs for the 2570103 holders are single pole, however, the manufacturer also makes a double pole version. The purpose of the double pole is to ensure that the two fuse elements are at an equal grounding potential. The double pole is often used when grounding is of particular importance, such as with reactive loads or transformers that can be affected by ground loops. It is also helpful to use the double pole in systems where two different current ratings are needed on different circuits.

Theholders’ working principle is quite simple. The fuse is placed within the holder and contacts are made between the two. When the system is powered, current flows thorough the fuses. The power flow is controlled by two mechanisms. The first is a time delay feature, which ensures that the fuse is not overloaded and the second is a current limiting feature, which prevents the fuse from drawing too much current.

The advantages of using 2570103 holders are numerous. The easy installation and removal of fuses, superior electrical continuity, as well as protection against short-circuiting makes this product a great choice for any application. Furthermore, the UL listing and National Electrical Code approval ensures quality and safety standards are strictly adhered to. The durable design also makes them dependable and reliable over the long-term.
