Siemens HNF361X delivers compact, heavy‑duty safety switching for reliable on/off isolation and overcurrent protection in the most demanding industrial and commercial settings.

Designed as a 3‑pole safety switch with a 30A, 600V rating, it provides clean, safe isolation for three‑phase power. The enclosure carries a NEMA 4X designation, meaning it’s built to resist dust, water, and corrosive environments—making it suitable for outdoor installs, wash‑down areas, and harsh facilities without compromising protection or performance.

• 3‑Pole, three‑phase disconnect: ensures complete isolation of all live conductors during maintenance or emergency stops, simplifying safety procedures.
• 30A at 600V: robust enough for common motor loads and branch circuits in commercial and light industrial applications.
• NEMA 4X enclosure: provides durable protection against the elements and corrosion, enabling reliable operation in challenging environments.
• Heavy‑duty construction: engineered for frequent operation in demanding facilities, delivering long service life and dependable performance.
• Maintained fusible switch in a compact form: a streamlined, space‑efficient solution that facilitates easy fuse replacement and ongoing maintenance.

Ideal for motor disconnects, panelboards, and branch circuit protection where space is at a premium and quick, secure isolation is required. This model supports equipment like conveyors, pumps, fans, compressors, and other three‑phase loads in manufacturing, processing, and commercial environments.

Why choose the HNF361X? It merges reliable isolation with overcurrent protection in a rugged, corrosion‑resistant package, reducing downtime and simplifying installation and service in harsh or outdoor settings. If you need a compact, easy‑to‑maintain safety switch that stands up to demanding conditions while keeping three‑phase systems safely isolated, the Siemens HNF361X is the practical, proven choice.
