GE TH4323R - 100A, 240V, 3-Pole, Fusible, Disconnect Switch

GE TH4323R is a rugged, fusible disconnect switch engineered for reliable on/off isolation and built-in overcurrent protection in demanding industrial and commercial settings. With a 100A rating, 240V operation, and a 3-pole configuration, this switch delivers precise control over three-phase equipment while keeping a compact, maintainable footprint that fits tight control panels and equipment rooms.

Why the TH4323R stands out

• Three-pole, 240V operation—designed to manage three-phase loads with dependable isolation and control for motors, pumps, conveyors, and other industrial equipment.
• 100A rating—handles common motor and equipment startup currents without compromising protection or performance.
• Fusible protection—integrates overcurrent protection directly into the disconnect, simplifying wiring and protection strategies in one installable unit.
• Compact, maintainable design—a footprint that fits crowded panels and service spaces, with straightforward maintenance workflow to minimize downtime during fuse changes or inspections.
• Rugged reliability—built to endure the rigors of industrial and commercial environments, delivering consistent performance across operating cycles and fault events.

Ideal applications

• Motor disconnects for fans, pumps, compressors, and conveyors in manufacturing or facilities environments
• Panelboards where a dedicated, fuse-protected disconnect is required for safety and code-compliant isolation
• Branch circuit protection in control cabinets and distribution enclosures where space is a premium

What problems it solves

When machines require a clear, controllable stop point with concurrent overcurrent protection, the TH4323R delivers. It ensures safe de-energization for maintenance, reduces exposure to live electrical components, and provides reliable protection against short circuits and overloads on three-phase circuits. The fusible design consolidates protection and isolation in one device, helping you meet electrical codes and streamline protective strategies without adding separate fusing devices.

How it compares to the needs of your system

For facilities balancing space constraints with protection requirements, the GE TH4323R offers a practical balance of performance and maintainability. It’s particularly well-suited when you need a dedicated, fuse-protected disconnect in a control panel or near motor loads, rather than a bulky, non-fused disconnect. Its 3-pole arrangement aligns with typical three-phase equipment, ensuring synchronized shutdown across all live conductors and reducing the risk of partial energization during service events.
