Siemens HNF361 Non-Fusible Indoor Disconnect Switch

Siemens HNF361 is a heavy‑duty, non‑fusible indoor safety switch designed to isolate three‑phase circuits up to 30 A at 600 V AC. This 3‑pole, 3‑wire device is housed in a rugged indoor NEMA 1 enclosure, making it suitable for installation inside control panels or equipment rooms where a non‑fusible disconnect is required. As part of Siemens’ VBII family of safety switches, the HNF361 provides a robust non‑fusible isolation path with a high short‑circuit rating of 200 kA, helping protect downstream components during faults. The model is available in indoor configurations, and a Solar Safety Disconnect variant exists under the HNF361PV family for PV installations. Typical applications include isolating motors, compressors, and other three‑phase equipment in indoor industrial settings where a reliable, code‑compliant disconnection is needed.
