NewTrend · DC circuit protection
Product overview
DM1z DC molded case circuit-breaker enquiry. Frame, current and pole options follow the original product table. Voltage and short-circuit ratings must be matched to the exact supplied version.
Technical selection summary
| Frame / current, A | DM1z-125: 10, 16, 20, 25, 32, 40, 50, 63, 80, 100, 125; DM1z-250: 100, 125, 160, 180, 200, 225, 250 |
|---|---|
| Pole count | 2P,3P,4P per original frame table. Unsupported1P options are removed. |
| Voltage and wiring | Original diagrams show different series-connected-pole arrangements and frame-specific dimensions. A voltage printed on one diagram does not establish every frame/pole configuration; order the exact rated version and use its matching diagram. |
| Breaking capacity | Actual per-frame/per-pole/per-voltage Icu/Ics matrix remains to be confirmed. Unqualified20/35/50kA claims are removed. The shared400A photograph marks35kA at DC60V; it does not establish35kA at DC660/750/1000V. |
| Outline / connection references | All original technical tables, pole connection drawings and mounting dimensions are retained below. Follow the model labels on each drawing. |
| Product image | Shared gallery photographs are series references and do not identify the selected current, frame, voltage or breaking-capacity version. |
The selected frame/current/poles define an enquiry, not a complete electrical order code. Confirm DC system voltage, prospective fault current, Icu/Ics, polarity and exact wiring before purchase or installation. Another manufacturer’s similar DC breaker table is not a guaranteed rating for this supply.
