But if the internal automatic reclose function is controlled by the pickup (only possible for 3-pole tripping: 110
Trip mode = 3pole only), the phase-selective pickup
signals of the external protection must be connected
if distinction shall be made between different types of fault. The general trip command then suffices for tripping
(No. 2746). Figure 2-165 shows a connection example.
