5SJ4 10A 1P Family: Compare
The 5SJ4 series shares the same DIN-rail modular form factor across ratings. Reader qualification of each candidate against specific fault current and coordination requirements is essential before selection.
| Spec | 5SJ4110-8HG40 (seed) | 5SJ4110-8HG41 | 5SJ4110-7HG40 | 5SJ4110-6HG40 |
|---|---|---|---|---|
| Current (A) | 10 | 10 | 10 | 10 |
| Voltage (V) | 240 | 240 | 240 | 240 |
| Poles | 1 | 1 | 1 | 1 |
| Mount | DIN Rail | DIN Rail | DIN Rail | DIN Rail |
| Trip Curve | 14K SAME PH | 14K D-TRIP | 14K SAME PH | 14K SAME PH |
| Similarity | — | 1.00 | 1.00 | 1.00 |
5SJ4110-8HG41 — Shares 10 A, 240 V, 1P, DIN Rail; differentiated by D-TRIP designation versus SAME PH.
5SJ4110-7HG40 — Matches 10 A, 240 V, 1P, DIN Rail; trail digit shifted from 8 to 7 within same family block.
5SJ4110-6HG40 — Matches 10 A, 240 V, 1P, DIN Rail; lower trail digit variant preserving identical core ratings.
The voltage rating shifts to 277 V in 5SJ4110-8HG42 (10K curve) and 5SJ4110-7HG42 (C-TRIP), suitable for single-phase US branch circuits. The 15 A variant 5SJ4118-8HG40 and 5 A variant 5SJ4111-8HG40 extend current coverage while retaining 1P/240 V / DIN Rail packaging.
Installation Guidance
Standard 35 mm DIN rail mounting with lever actuator for manual operation. Bulk packaging reflects typical panel-builder quantities; verify fault current rating against upstream protective device coordination study before deployment.
