Key Differences Explained
-
Neutral Presence
-
HF364N: Only model with a solid neutral (for 4-wire systems).
-
HNF364/HF364: 3-wire only (no neutral).
-
-
Fused vs. Non-Fused
-
HF364N & HF364: Include fuse protection (200kA fault rating with Class R/J).
-
HNF364: Disconnect-only (relies on upstream breakers/fuses).
-
-
Applications
-
HF364N: Service entrances, 3-phase + neutral loads (e.g., HVAC, industrial panels).
-
HF364: 3-phase circuits without neutral (e.g., motors, pumps).
-
HNF364: Simple isolation (maintenance, motor disconnects).
