The drawings show a 200A body marking for DSTB/80. Its electrical selection rating is 180A as listed above.
| Model | Flexible conductor | Flexible conductor with ferrule | Solid conductor | UL wire range |
|---|---|---|---|---|
| DSTB/8 | 1.5–8mm² | 1.5–8mm² | 1.5–8mm²; 10mm² solid also specified | 12–8AWG |
| DSTB/22 | 4–22mm² | 4–22mm² | 2.5–22mm² | 22–4AWG |
| DSTB/38 | 4–38mm² | 4–38mm² | 2.5–38mm² | 20–2AWG |
| DSTB/80 | 4–95mm² | 4–95mm² | 4–75mm² | Not specified |
Keep the solid and flexible conductor limits separate. Use the stated terminal screw and torque for the selected model; a mounting fastener is not interchangeable with a conductor-clamping screw.

|---|---|---|---|---|
| DSTB/8 | 13×(N−1)+36.10 | 26.00 | 42.00 | 18.05 |
| DSTB/22 | 16×(N−1)+47.00 | 31.80 | 47.00 | 23.50 |
| DSTB/38 | 21×(N−1)+50.00 | 36.80 | 56.00 | 25.00 |
