Siemens GF221N 30A 2P 240V Safety Switch, Fusible | AmpState

Meet the Siemens GF221N — a 30A, 2-pole, 240V fusible safety switch engineered for reliable equipment disconnect and precise isolation right at the point of use. This is the smart choice for retrofit projects and maintenance planning where maintaining a consistent part number matters, reducing downtime and streamlining inventory.

Key details at a glance:

• Manufacturer: Siemens
• Part Number: GF221N
• Product Type: Safety Switch
• Amperage: 30 A
• Poles: 2
• Voltage: 240V
• Fusible: Yes — the GF221N is designed as a fusible safety switch, combining disconnection capability with protective fusing in a single unit
• Availability: Available from AmpState

Why this matters in the real world

• Safe, reliable isolation — quickly disconnects power to equipment for maintenance, servicing, or emergency stops, reducing risk for personnel and downtime for machinery.
• Retrofit-friendly — designed to fit into existing installations where the part number must stay consistent, making upgrades or replacements smoother without rewiring or redesigns.
• Point-of-use protection — installed at the device or machine level, providing targeted protection exactly where it’s needed most.
• Practical for complex systems — with a two-pole configuration, you can isolate both hot legs of a 240V circuit, ensuring complete circuit disconnection.

Ideal use scenarios

• Retrofitting older lines where a consistent GF221N part number simplifies maintenance schedules.
• Equipment disconnects in manufacturing cells, conveyors, pumps, and motor-driven systems running on 240V.
• Maintenance planning for machine decks and control panels where quick, safe isolation minimizes downtime.
• New installations requiring a compact, reliable fusible safety switch with clear isolation points at the point of use.
