Siemens GF221NRA - 30A, 2-Pole, Fused Disconnect Switch

Siemens GF221NRA is a rugged 30A, 2-pole fused disconnect switch designed for industrial and commercial environments where safe electrical isolation is non-negotiable. Built to endure demanding daily use, it supports proper lockout/tagout procedures and delivers dependable disconnection under load, ensuring long-term durability and peace of mind for your electrical system.

With a two-pole design, the GF221NRA isolates both hot conductors simultaneously, preventing partial energization during maintenance or service. The integrated fuses provide targeted protection, helping to contain faults at the source and protect downstream equipment such as motors, conveyors, pumps, and control circuits.

• Two-pole isolation: ensures complete de-energization of the circuit for safe service work.
• 30-amp rating: appropriate for mid-range industrial loads without unnecessary trips.
• Fused protection: built-in fuses offer reliable fault interruption and equipment protection.
• Lockout/tagout compatibility: supports standard safety procedures to keep technicians safe during maintenance.
• Durable construction: designed for harsh environments, delivering dependable performance over time.
• Seamless integration: straightforward installation within existing panels and wiring schemes.

This fused disconnect switch is an ideal solution for electrical teams responsible for machine uptime, facility automation, and critical process lines. It’s well-suited for panel builders, OEMs, and maintenance crews seeking reliable isolation and protection without sacrificing ease of use.
