Siemens HF363NR - 100A, 600V, Fused Disconnect Switch

The Siemens HF363NR fused disconnect switch is built for serious industrial and commercial electrical isolation. Designed to perform reliably under load, it provides a safe, obvious disconnect path while supporting lockout/tagout procedures to protect maintenance teams. With a 100A amperage rating and a 600V maximum, this device handles demanding circuits with confidence.

Engineered for durability, the HF363NR uses a NEMA 3R enclosure, delivering weather resistance and protection from dust, rain, and other elements. This makes it a solid choice for outdoor equipment rooms, service entrances, or any installation where environmental exposure is a factor.

Integrated fusing offers immediate overcurrent protection, simplifying electrical protection schemes and reducing the number of separate components you need on site. When used as a service disconnect or as part of a larger control system, it ensures safe, intentional disconnections without surprises—crucial for routine maintenance and emergency shutoffs alike.

Who benefits most from the Siemens HF363NR? Electricians, facilities engineers, panel shop integrators, and maintenance teams responsible for reliable power isolation in harsh environments. It’s ideal for commercial buildings, manufacturing floors, outdoor equipment, and any application where a robust, code-conscious disconnect is essential.
