Reading the Designation One More Time
DILM25-10: 25A frame, 10A AC-3 rating, with a 230V AC coil in the base designation. This is the mainstream 230V single-phase-supply frame in European panel work, and it is the version most often specified when an incumbent brand is being re-sourced for price.
The variables that decide whether an alternative is a like-for-like replacement: frame size (25A), AC-3 rating, coil voltage (230VAC), auxiliary contact count, and terminal layout. Change any one of those and you have a different part, not a substitute.

Cross-Reference Table for Panel Builders
| Parameter | DILM25-10 230V equivalent | What to verify before substituting |
|---|---|---|
| Frame / current | 25A frame | Incumbent frame current must match or exceed the load |
| AC-3 rating | 10A at 400/415V | Compare AC-3, not AC-1 — they are not the same number |
| Coil voltage | 230VAC | Confirm the panel control supply, not the load voltage |
| Auxiliary contacts | 1NO standard | Add-on blocks are a separate SKU |
| Terminals | Screw terminals | Check conductor size against your panel wire gauge |
| Mounting | DIN rail | Verify available enclosure depth |
Why Distributors Re-Source This Frame
The honest reason is margin on a high-turnover part. The honest risk is that a substitution with a different auxiliary contact count or a different terminal arrangement turns a five-minute swap into a panel rework. The way to avoid that is to fix the specification before you shop the price: write down the frame, the AC rating, the coil voltage, and the aux count, then request quotes against that frozen specification.
