Siemens GF325NR 400A 3P 240V Safety Switch, NEMA 3R, Fusible | AmpState

From Siemens, the GF325NR 400A 3P 240V Safety Switch is built to deliver reliable equipment isolation right at the point of use. This fusible, three-pole switch is purpose‑built for everyday electrical work, offering robust protection and straightforward maintenance during retrofit projects and routine service.

Why the GF325NR stands out

• 400 A, 3-Phase, 240 V — a heavy‑duty disconnect that handles demanding industrial loads with clear, decisive isolation.
• NEMA 3R enclosure — designed to withstand outdoor and damp environments, protecting the internal protection and enabling safe operation in varied conditions.
• Fusible design — integrated fusing provides immediate overcurrent protection, eliminating the need for separate fuses and simplifying control wiring and maintenance.
• Part of a consistent footprint — the GF325NR is ideal for retrofits where keeping the same part number simplifies stock, servicing, and future planning.
• Siemens reliability — built to endure daily use in industrial settings, backed by Siemens engineering and support from AmpState.

Practical uses and ideal applications

The GF325NR shines in environments where dependable isolation is critical. Use it to disconnect large equipment at the point of use, such as outdoor pumping stations, outdoor HVAC installations, conveyor systems, motors, and other three‑phase machinery. Its NEMA 3R rating makes it a smart choice for outdoor enclosures or damp locations, where protection against rain, ice, and incidental moisture matters most. For retrofit projects, your maintenance planning benefits from a part number you can rely on, reducing downtime and parts mismatch.

What this means for you

• Faster maintenance planning with a familiar, consistent part number that aligns with existing spare inventories.
• Enhanced safety through a dedicated disconnect switch that provides clear isolation for servicing and emergencies.
• Weather-ready protection thanks to the NEMA 3R enclosure, reducing weather-related concerns for outdoor or damp installations.
• All‑in‑one protection with a fusible design, delivering overcurrent protection alongside the disconnect function.
