GE TGN4321R - 30A, 240V, 3-Pole, Heavy-Duty, Fusible, Switch

Meet the GE TGN4321R—a robust, 3‑pole fusible switch engineered for reliability in demanding industrial and commercial environments. Designed to deliver dependable on/off isolation and integrated overcurrent protection, this heavy‑duty disconnect is built to keep your equipment safe and your operations moving smoothly.

Why this fusible switch stands out

• 3‑Pole, 3‑phase design ready to handle three‑phase loads with precise control, ideal for motor-driven equipment, conveyors, and HVAC systems.
• 30A at 240V capacity provides strong protection for branch circuits and small to mid‑size motor circuits without unnecessary overspec.
• Fusible protection integrates overcurrent protection directly into the switch, reducing the need for separate fusing components and simplifying control panel design.
• Heavy‑duty construction built to endure the rigors of busy industrial spaces and commercial installations, ensuring long service life even under frequent switching.
• Compact, maintainable design offers straightforward servicing and fuse replacement, helping minimize downtime during routine maintenance or fault response.

Ideal applications and use cases

• Motor disconnects for pumps, fans, compressors, and other three‑phase equipment—providing a safe, code‑compliant isolation point during maintenance.
• Panelboard protection where a single, integrated switch and fuse assembly reduces panel complexity and improves reliability.
• Branch circuit protection in light‑to‑medium industrial installations, machinery enclosures, and commercial electrical rooms.

What problems it solves

• Eliminates the need for separate fusing in some layouts, simplifying control schemes and reducing component count.
• Delivers fast, clear isolation to prevent accidental energization during service or fault conditions.
• Supports consistent performance in environments where frequent switching and motor loads are common.

How it compares to alternative solutions

Compared to standalone switches or non‑fusible disconnects, the GE TGN4321R combines controlled isolation with built‑in overcurrent protection in a single, compact package. This integration can streamline panel design, simplify compliance checks, and reduce wiring complexity—without sacrificing performance or accessibility for maintenance.
