Siemens GF223NR - 100A, Fused Disconnect Switch

The Siemens GF223NR 100A Fused Disconnect Switch delivers robust electrical isolation for industrial and commercial environments where safe, reliable disconnection under load is non‑negotiable. Built to integrate with standard electrical gear, it supports lockout/tagout procedures and provides dependable protection during servicing and maintenance of heavy loads.

Key advantages of the GF223NR

• 100A current rating — confidently handles medium to high‑demand circuits while maintaining clear separation when required.
• Fused disconnect design — combines isolation with overcurrent protection, helping to contain faults and protect downstream equipment.
• Lockout/Tagout readiness — engineered to support safe servicing routines, giving technicians a reliable method to secure the circuit during work.
• Durable, long‑term operation — built to endure the rigors of industrial and commercial environments with minimal maintenance.
• Seamless integration — compatible with existing electrical safely‑isolating schemes, enabling straightforward installation in panels, MCCs, or service entrances.

Ideal use cases

• Industrial facilities and manufacturing lines requiring dependable isolation for routine maintenance and fault prevention.
• Commercial systems with high‑demand motors, large conveyor sections, or HVAC equipment where disconnection under load is necessary.
• Service entrances and distribution panels where lockout/tagout procedures ensure worker safety during servicing.
• Motor control centers (MCCs) and component cabinets needing a reliable fused disconnect to protect downstream circuits.

Why this fused disconnect stands out

Unlike non‑fused disconnects, the GF223NR delivers integrated overcurrent protection without adding separate protective devices, reducing the number of components you need while streamlining maintenance. The fused pathway ensures that, when a fault occurs, the fuse responds quickly to interrupt the circuit, helping to minimize damage and downtime. With Siemens’ reputation for reliability, this disconnect switch is a trusted choice for facilities that prioritize consistent performance and worker safety.

Practical tips for installation and use

• Verify compatibility with your system’s voltage, wiring configuration, and conductor sizing before installation.
• Plan for lockout/tagout procedures by provisioning appropriate hasps and tagging points on the switch housing to safeguard maintenance personnel.
• Schedule fuse replacement by qualified personnel only; inspect fuses for signs of wear or contamination during routine maintenance.
• Use as part of a comprehensive electrical isolation strategy to reduce arc energy risk and ensure safe de‑energization during servicing.

Equip your facility with the Siemens GF223NR 100A Fused Disconnect Switch for dependable, code‑compliant electrical isolation that supports safe maintenance, protects equipment, and keeps your operations running smoothly.
