Siemens 5SJ42208HG41 — 20 A, 2-Pole DIN Rail Miniature Circuit Breaker
Catalog Comparison — 5SJ4 Series Screening
The table below presents the seed part alongside three in-catalog alternatives from the same Siemens 5SJ4 family. All parts share the same mounting method, pole count, and lever actuator type. Shared spec fields are shown; differing values are highlighted to aid screening. None of the listed alternatives carry an OEM interchange endorsement.
| Spec | 5SJ42208HG41 (seed) | 5SJ4220-8HG42 | 5SJ42207HG41 | 5SJ4225-8HG42 |
|---|---|---|---|---|
| Current Rating | 20 A | 20 A | 20 A | 25 A |
| Poles | 2 | 2 | 2 | 2 |
| Mounting | DIN Rail | DIN Rail | DIN Rail | DIN Rail |
| Actuator | Lever | Lever | Lever | Lever |
| Illumination | None | None | None | None |
| RoHS | Non-compliant | Non-compliant | Non-compliant | Non-compliant |
| Package | Bulk | Box | Bulk | Box |
| Similarity | — | 1.0 | 1.0 | 1.0 |
Why Each Alternative Is Similar
5SJ4220-8HG42 shares the same 20 A rating, two-pole configuration, and DIN Rail mounting as the seed. The MPN suffix differs only in the trailing model-code segment. Both carry multi-standard approvals (CCC, CE, EAC, UL) with bulk or box packaging variants within the same series.
5SJ42207HG41 matches on current (20 A), poles (2), and mounting (DIN Rail). The series designation indicates a related trip-characteristic variant within the Siemens 5SJ4 catalog family.
5SJ4225-8HG42 retains the two-pole DIN Rail form factor and lever actuator of the seed, with the primary difference being an increased current rating of 25 A. The MPN prefix structure places it in the same Siemens 5SJ4 product family.

The 5SJ4 series uses a standardized lever Actuator Type for manual operation and is packaged in bulk quantities for panel builder stock flow.
Physical Integration Notes
The DIN Rail mounting form factor is common across the 5SJ4 series, allowing a consistent panel layout when mixing 20 A and 25 A ratings on the same rail. All listed parts use the same lever Actuator Type, which simplifies operator interface design across a mixedrating assembly.
No specific IP rating, cutout dimension, or terminal torque specification is present in the on-record data.
