Siemens GF223N - 100A, 240V, 2-Pole, Fused Disconnect Switch

The Siemens GF223N is a rugged, industrial-grade fused disconnect switch designed to deliver safe and reliable electrical isolation where uptime and personnel safety matter most. With a 100A rating at 240V and a compact 2-pole design, it provides a clean, code-compliant means to disconnect power to motors, panels, and other heavy-duty equipment during maintenance or servicing.

Why the GF223N stands out

• Exacting overcurrent protection: The integrated fuse protection ensures quick disconnection in fault conditions, helping to prevent equipment damage and reduce downtime.
• Secure lockout/tagout compatibility: Built to support lockout/tagout procedures, the GF223N helps you maintain safe work environments by preventing accidental re-energization during servicing.
• dependable under-load disconnection: Designed to reliably interrupt circuits even while equipment is energized, minimizing backfeed risks and ensuring a true isolation point for maintenance.
• Industrial durability: Engineered for demanding commercial and industrial environments, delivering long-term performance in challenging conditions.
• Compact 2-pole configuration: Two clean, easily wired poles provide straightforward integration into motor circuits, control panels, and distribution feeds without unnecessary bulk.

Ideal use cases

• Motor control circuits in manufacturing lines, pumps, and compressors where a secure isolation point is essential for maintenance.
• HVAC and large mechanical systems that require a clear, temporary disconnect to service safely.
• Electrical service entrances or panel feeds where a dedicated fused disconnect enhances protection and reliability.
• installations that must comply with lockout/tagout protocols and clear, verifiable de-energization during work shifts.

Practical guidance for getting the most out of your GF223N

To maximize safety and reliability, pair the GF223N with correctly-rated fuses that match the circuit’s load and inrush characteristics. When performing maintenance, follow standard lockout/tagout procedures to ensure the device remains de-energized throughout the service window. Regular inspection of fuse elements and terminal connections helps prevent nuisance outages and extends service life. If you’re upgrading from a non-fused disconnect, the GF223N offers a clear, auditable isolation point that simplifies compliance and enhances safety for routine maintenance and emergency readiness.
