Fuseholders are electrical devices specifically designed to hold and supply the correct electrical load to a safety system. The 03453RF8H Fuseholder is an example of such a device. It is composed of two independent contacts and a contact arrangement configured to assist in the current distribution when in use. The fuseholder also provides over-voltage protection.
The 03453RF8H Fuseholder is created to be a direct fit product in line applications. The device features two independent contacts that are designed for fast, convenient installation. This helps the device to be easily installed in the electrical line. The product utilizes mechanical interlocking. This provides an easy mechanical connection across the two contacts meaning the product will stay in place while being used. The two contacts also feature plated steel and nickel for the spring construction. This helps to reduce wear and assist in the current distribution.
The over-voltage protection that the 03453RF8H Fuseholder provides is beneficial when the electrical load passing through the device is intensifying. This helps to reduce any damage to the system, and assists in the prevention of accidental electrocution from strong current flow. The over-voltage protection turns off the flow of current the moment the voltage exceeds the set limit. This ensures that the device is not damaged from the overload of electricity. The product also has two different sizes that can be chosen to fit the needs of a specific current level.
In terms of safety measures, the 03453RF8H Fuseholder utilises Visible Bridge contacts. This ensures that the product visually sets apart how much current is passing through the device. This is particularly beneficial to ensure that no overloads or heating occur. The product also utilizes an IC contact design in order to maximize the connection with any components that are being used. This reduces the risk of interruptions with the current, therefore reducing the potential of accidents.
The 03453RF8H Fuseholder works using the principle of a switch. The switch triggers the flow of electricity once the contact points are completed. It is when the contacts are made that the current flows, thus connecting the electrical system by completing the circuit. The contact points are created by the metal ridges that are located beneath the plastic casing. These ridges allow the two contacts to be connected together so the energy is able to flow through the complete circuit. When triggered, the fuseholder will effectively hold the established current and not release it until appropriate measures have been taken. This means that over-voltage protection is engaged and the risk of a surge is diminished.
The working principle of the 03453RF8H Fuseholder is based on a switch system, which is beneficial as it allows the device to be triggered without physical contact. This helps to ensure that the current flowing through the device is not suddenly disrupted. Additionally, the product provides over-voltage protection and is designed with plated steel construction meaning the device will stand up to daily use. Finally, the product has a two contact configuration for two separate levels of current flow.
