Reader must qualify any alternate independently; numeric similarity here reflects catalog-parameter proximity only.
Why similar (shared-axis tie + optional contrast)
- 5SJ4111-7HG41 — Same 240 V, 5 A, 1-pole, DIN-rail mount, Bulk package. Swap 14K C-TRIP for the seed's 14K SAME PH; identical agencies and RoHS status.
- 5SJ4111-7HG42 — Same current, pole count, and certifications. Voltage steps to 277 V and trip shifts to 10K C-TRIP; used where higher line-to-neutral ratings apply.
- 5SJ4111-8HG41 — Same core rating (5 A, 1-pole, 240 V) and bulk package. D-TRIP characteristic replaces C-type; some markets list UL489 where the seed carries plain UL.

The 5SJ4 family occupies the mid-range DIN-rail miniature breaker slot in Siemens' catalog. SAME PH designation in the title signals a short-time self-protection characteristic; "14K" defines the instantaneous trip band (K-curve, typically 10–14× nominal current for inductive loads). Bulk packaging implies bare part without retail blister; panel builders order by quantity for DIN rail installation in distribution panels.
