• Under-Load Disconnection: Provides a trustworthy, clean break even when equipment is energized, minimizing downtime and safeguarding personnel.
• Industrial-Grade Durability: Built to withstand frequent operation, with construction that holds up in harsh environments over time.
• Precise 100A Protection: An ideal fit for mid‑range distribution panels and equipment protection tasks within commercial facilities and light manufacturing.
• Siemens Reliability: Backed by the Siemens heritage of engineering excellence, ensuring availability of parts, support, and long-term performance.

Ideal applications and use cases

• Power distribution panels in manufacturing plants, warehouses, and processing facilities
• Maintenance shutdowns and routine servicing in commercial buildings
• Safety-critical isolation points in equipment rooms where dependable disconnection is required

How this fused safety switch improves your operations

By combining fused protection with a design that prioritizes safe isolation, the GF223N reduces arcing risk during disconnection and provides a clear, verifiable path to de-energize circuits. This translates to fewer safety incidents, smoother maintenance workflows, and more predictable equipment reliability. In contrast to non-fused or unprotected switches, the GF223N adds a critical layer of protection, helping you meet safety best practices without sacrificing performance.
