Description
The TU_ series covers compact feed-through models with 20×5, 30×10 and 40×10 mm busbars, Ø16, Ø22 and Ø30 mm cable and currents of roughly 50–1000 A. TUC_ units have windows for 30×10, 40×10, 50×10, 60×10 and 80×30 mm busbars, Ø25–Ø65 mm cable and currents up to 3000 A, and the 0.5S, 0.2 and 0.2S versions give higher accuracy; TUC40-1 has a 40 mm window. TL_ is chosen for 750–6000 A with 100×20, 100×30 and 100×60 mm busbars. The slim-profile TU20PS, TU30PS, TU40PS, TU50PS, TU60PS, TU80PS, TU100PS and TU125PS are designed for 20×6–125×50 mm busbars, Ø18–Ø70 mm cable and 60–4000 A. TU_PS-3 combines three phases in one housing, and TU20PS-1 is a miniature model for 30–400 A. TU100PSH, for a 100×30 or 80×50 mm busbar (cable Ø85), has two independent secondary windings with sealable terminal blocks.
How to choose
First determine the primary current and the way the conductor is run. For cable up to Ø30 mm and about 1000 A, TU_ is enough; for busbars up to 80×30 mm and 3000 A, TUC_ is suitable; and up to 6000 A, TL_ is used in 0.4 kV boards and busways. In a tight cabinet look at TU_PS, and for three phases in one housing, at TU_PS-3. Classes 0.5, 1 and 3 are standard, while 0.2S, 0.2 and 0.5S are ordered separately. If the cable cannot be disconnected, look at the split-core TA_P for 20–5000 A.
