Terminal Blocks - Accessories comprise items such as end plates, mating bases, covers, jumpers and bridges which aid the organisation and planning of an electrical installation. This article looks at a particular type, known as the 3211197 Terminal Block.As with any piece of equipment used in electrical installations, the 3211197 Terminal Block has a field of application and a working principle. In brief, these are:Field of ApplicationThe 3211197 Terminal Block is designed for the connection of current carrying wires, to establish electrical circuits. It is suitable for high current, low voltage applications, making it ideal for applications such as power distribution in residential and commercial buildings.Working PrincipleThe 3211197 Terminal Block is designed to make and break the electrical connection between different conductors. It incorporates a number of components which allow this to take place.The main component on the 3211197 Terminal Block is the contact member, typically made from copper. This is the part which actually carries the current and makes and breaks the electrical connection. It is held in place by a base mount and can move as required.Also on the 3211197 Terminal Block are a number of insulation parts, which protect the contact member from short circuits and other kinds of damage. These insulation parts include plastic housing and an isolated cover.In order to create and break an electrical connection, the contact member on the 3211197 Terminal Block must move. This can be done either manually or mechanically, depending on the requirements of the application.If the contact member is to be moved manually, then the user can do this with the aid of a jump ring. This is a short piece of metal, typically made from brass or copper, which is used to connect two parts of a circuit.The jump ring is inserted into the terminal block and then the terminal block is connected to the wire. When the ring is moved, it will make or break the electrical contact.On the other hand, if the contact member is to be moved mechanically, then the 3211197 Terminal Block must be fitted with a bridge. This is a metal component, which is attached to the contact member. The bridge moves in unison with the contact member, allowing the user to make and break connections quickly and easily.For added safety, the 3211197 Terminal Block also comes with a locking mechanism. This prevents any accidental movement of the contact member.In summary, the 3211197 Terminal Block is an essential piece of electrical equipment. It is designed for high current, low voltage applications and can be used to make and break electrical connections manually or mechanically. It offers a high degree of protection via its insulated parts and a locking mechanism.
