The TR8-1200 is a TUR distribution board designed for 1000 kVA transformer connections, making it the highest-capacity model in this range. Its dimensions are 1450 x 900 x 540 mm, with recommended fixing centres of 760 ± 20 mm horizontally and 590 mm vertically. It requires 4 x 240 mm² or 2 x 630 mm² aluminium cables per phase, and 2 x 240 mm² or 1 x 630 mm² for the neutral. For upstream connection, it uses three U-shaped interphase connection brackets and six connection plates, tightened to 30 ± 5 Nm. The 1200 A switch handle is connected with two M8x20 screws with captive washers in the right upright inserts. This model is intended for demanding high-power transformer-to-distribution connections.
