Reader must qualify alternates independently; numeric similarity reflects catalog-parametric overlap, not application fitness.
- HF362SS: Same 60 A / N4X rating with 316 stainless steel hardware for enhanced corrosion resistance in caustic environments. Shares series, voltage, and current.
- HF362J: Drop-in functional equivalent rated for NEMA 12 environments (indoor industrial, dust-protected); differs only in enclosure rating.
- HF368S: Scales to 100 A while retaining N4X and 600 V; useful when branch protection exceeds 60 A.
- HF363S: Also 100 A in N4X; same family, higher ampacity, same voltage class.
Family Position — US2 Series HF362x
The HF362x prefix identifies Siemens box-mount heavy-duty safety switches for fusible branch circuits. Suffix variations encode enclosure type (S = N4X, J = N12, RL = N3R, SCHW/SCH = handle/inscribed options, PNL/PN = alternate hardware supplier). The 60 A rating here is the minimum frame size; the 100 A variants (HF363S, HF368S) use the same form factor.
