See Figure 1. Dimensions are in millimetres with exception Terminal thread 8-32 UNC.4.4 Panel mounting Panel cut-out The panel cut-out is in accordance with the designation TR 6083C202. Spacing 20 mm horizontal and 35 mm vertical from the centre of the mounting holes. Panel thickness 1mmto3mm. The metallic front plate of the breaker (mark 15 on Figure 1) is an electrical connection to neutral. For this purpose the panel mounting means must ensure a good electrical continuity to neutral. In case of panel isolated from neutral a rear wire can be used to connect neutral to terminal 6 (see Figure 1).BS EN 4838-005 pdf download.
