DIN 42530 1kV 630A Ceramic Bushing DT 1/630
Low Voltage Transformer Bushings
Product Overview
A DIN 42530 low voltage bushing catalogued as DT 1/630 at 1 kV and 630 A. The published table gives a 45 mm tank hole size, 75 mm creepage and an M20 stem connection. Across the DIN 42530 range the tank hole grows with current, from 45 mm at 630 A to 90 mm at 3150 A, and the stem connection steps from M12 through M20, M30, M42 and M48.

Comparison
How It Compares
| DT 1/250 | The 250 A version uses a 60 mm creepage and an M12 stem. Tank hole and stem change with every step in current, so the terminal board has to match. |
|---|---|
| DT 1/3150 | The 3150 A version needs a 90 mm tank hole and an M48 stem at the same 75 mm creepage. |
Use guide
Before You Order And After It Arrives
- Measure the tank hole and match it to the 45 mm figure
- Confirm the M20 stem suits your busbar connection
- Do not assume creepage carries across current ratings
- Order gaskets with the bushing when replacing
