Wider TUR distribution board for 630 kVA transformers. Dimensions 1450 x 900 x 450 mm, fixing centres 760 ± 20 mm horizontal and 590 mm vertical. Same cable options as TR5-1200I: 2 x 240 mm² or 1 x 630 mm² per phase. More internal space for installation and monobloc feeders.
The TR8-1200I is a TUR distribution board for 630 kVA transformer connections, featuring a wider format of 1450 x 900 x 450 mm and recommended fixing centres of 760 ± 20 mm horizontally and 590 mm vertically. It supports the same cable configurations as the TR5-1200I: 2 x 240 mm² or 1 x 630 mm² per phase, and 1 x 240 mm² or 1 x 630 mm² for the neutral. The wider design provides more internal space for installation and for mounting monobloc outgoing feeders. It also includes the main switch handle, lockable open position, and options such as protection screens and reservation panels. It is suitable for installations that require a larger layout while maintaining 630 kVA capacity.
