The various types ofterminals are constant dimensions for each size circuit-breaker: normally advisable to exploit the whole contact surface the terminal, the width the connection busbars should the same that the terminal. some cases, reductions the width of the connection relation that the terminal are allowable shown the following examples. Different connection capacities can obtained adjusting the thickness and number busbars parallel. ------------------------------------------------------------------------------------------------------------------------------------------ P ositioning the first anchoring baffle the busbars according the rt-circuit current Anchoring the switchgear HORIZONTAL VERTICAL p + + P E1-E2 E3-E4-E6 E1-E6 HORIZONTAL 250 150 - VERTICAL 250 150 - FRONT 250 FLAT 250 Fig. 11/158 .
