5. Electrical connections

5.1. Connections to the power circuit

5.1.1. Shapes of the terminals

Note

The drawings are provided to show the type of terminal in graphic form. The exact shape of the terminals is given in the “Overall

dimensions” chapter.

5.1.2. Examples of positioning the connection busbars according to the types of terminals

The connection busbars enable the connection between the terminals of the circuit-breakers and the busbars of the switchgear. Their

sizing must be carefully studied by the switchgear designer. Some examples of possible constructions in relation to the shape and

size of the circuit-breaker terminals are given in this paragraph. The various types of terminals are of constant dimensions for each

size of circuit-breaker: it is normally advisable to exploit the whole contact surface of the terminal, so the width of the connection

busbars should be the same as that of the terminal. Different connection capacities can be obtained by adjusting the thickness and

number of busbars in parallel. In some cases, reductions in the width of the connection in relation to that of the terminal are allowable

as shown in the following examples.
