ECT-21.25 Current Transformer

ECT-21.25 current transformer for 1500–7000A primary current, accuracy classes 0.2 to 1, double seven-bar busbar configuration, 250mm outer width. The ECT-21.25 is the highest-capacity model in the range, rated for primary currents from 1500 A to 7000 A on a double seven-bar 125×10 mm busbar configuration, in a 250 mm outer width. It carries burden ratings from 10 VA to 45 VA across accuracy classes 0.2, 0.5/0.5s, and 1, purpose-built for large industrial switchgear, main generator and transformer protection, and any application running very high busbar currents.
