Siemens GNF221A General Duty Safety Switch

🔌 What it is

A Siemens 30-amp, 2-pole, 240V non-fusible general-duty safety switch / disconnect used to manually disconnect power to equipment for servicing or emergency shutoff.

🧾 What the model means

• GNF → General Duty, Non-Fusible
• 221 → 2-pole, 2-wire configuration
• A → Series / revision designation

⚡ What it does

This disconnect:

• Provides a manual ON/OFF disconnecting means for equipment
• Allows safe lockout/shutoff before maintenance
• Does not contain fuses—overcurrent protection must be upstream at the breaker/panel
• Typically mounted near equipment requiring a service disconnect

Manufacturer listings describe it as a 30A, 240V, 2-pole non-fusible indoor safety switch.

🏠 Typical uses

• Air conditioner condenser disconnects
• Water heater disconnects
• Small motor disconnects
• HVAC equipment shutoff
• Dedicated appliance disconnecting means

🧠 Simple explanation

This is a 30-amp disconnect switch that lets you manually shut off 240V equipment locally for servicing, but it does not provide fuse protection itself.

🔧 Key takeaway

• 30A rated
• 2-pole / 240V
• Non-fusible (breaker/fuse protection must be elsewhere)
• Indoor NEMA 1 enclosure
• Common for HVAC and equipment disconnect applications
