Technical selection summary
| Brand and series | DELIXI ELECTRIC CDM3LT |
|---|---|
| Product type | Transparent residual-current moulded-case circuit breaker |
| Frame / current references | 125 and 250 frames; documented rated-current references span 16–250 A according to frame and version |
| Pole configuration | 4P with three protected poles; specify the A/B neutral arrangement |
| Neutral references | A: neutral not switched; B: neutral switched |
| Release references | 2: magnetic-only release; 3: thermomagnetic release |
| Protection application | Distribution protection or the specified motor-protection version |
| Residual-current adjustment groups | 30 / 100 / 300 mA or 100 / 300 / 500 mA, selected by the complete code |
| Delay restriction | The 30 / 100 / 300 mA group is non-delay only. Other delay references require the matching version; fixed-delay products are special-order in the guide. |
| Non-actuating-time references | Default: non-delay; delay group 1: 0.1 / 0.2 / 0.3 s; delay group 2: 0.4 / 0.5 / 1 s. Confirm operating conditions for the exact product. |
| Operation and mounting | Hand operation; fixed front-panel wiring reference |
| Breaking / accessory selection | Confirm actual breaking performance from the exact nameplate and data; select shunt, auxiliary and alarm accessories separately |
The residual-current values are adjustment groups tied to the delay version, not freely interchangeable settings across every product. Magnetic-only and thermomagnetic releases also differ. Confirm the complete CDM3LT code, actual rated current, A/B neutral, release, residual-current group and delay before ordering.
Typical applications
- Low-voltage distribution circuits using the matching residual-current MCCB
- Motor circuits with the specifically selected motor-protection release
