Siemens GF323N - 100A, 3-Pole, Fusible, Switch

Meet the Siemens GF323N—the dependable 100A, 3-Pole Fusible Switch designed to deliver reliable on/off isolation and robust overcurrent protection in demanding industrial and commercial environments. This compact, maintainable disconnect switch is built to keep critical equipment safe while simplifying panel integration.

Why the GF323N stands out

• Three-pole, 100A fused design combines fast isolation with reliable overcurrent protection, safeguarding motors, feeders, and downstream circuits in a single, space-efficient package.
• Fusible protection provides coordinated interruption capabilities, allowing you to select the appropriate fuse type to match your load profile and protection strategy.
• Compact form factor fits neatly into panelboards and restricted enclosures, helping you maximize enclosure real estate without sacrificing protection.
• Maintanable by design with accessible fuse elements and straightforward wiring layout, reducing downtime during fuse replacement or service checks.
• Ideal for motor disconnects and branch circuits as a dedicated, all-in-one solution that isolates equipment safely while protecting downstream components from faults.

Practical applications and use cases

• Motor disconnects in manufacturing lines where rapid isolation is essential for maintenance and safety.
• Panelboard feeders requiring integrated overcurrent protection to prevent cascading faults in heavy-load applications.
• Branch circuit protection in commercial equipment rooms where space is at a premium and reliability is non-negotiable.
