GE THMC31 - 30A, 600V, 3-Pole, Fusible, Switch

Meet the GE THMC31—a robust 30A, 600V, 3-Pole Fusible Switch built for dependable isolation and overcurrent protection in demanding industrial and commercial environments. This compact, maintenance-friendly switch delivers precise control over your three-phase power, helping you protect equipment, reduce downtime, and keep critical systems running smoothly.

Why the THMC31 stands out

• Three-pole, 600V protection—designed for three-phase circuits, ensuring full-phase isolation and coordinated protection across all legs of your motor or equipment load.
• Fusible protection integrated with switching—the fusible design provides deliberate overcurrent protection while offering a straightforward path to restore service after fuse replacement, helping you control fault currents and minimize collateral damage.
• Compact, maintainable design—engineered for tight spaces and easy service, so swapping fuses or performing routine maintenance doesn’t derail your operations.
• Versatile application fit—ideal for motor disconnects, panelboards, and branch circuit protection where a reliable, space-efficient fusible switch is required.

Ideal use cases

• Motor disconnects on conveyors, pumps, fans, and compressors in manufacturing or processing facilities
• Feeders to panelboards in switchgear assemblies where clear isolation and quick fault clearance matter
• Branch circuit protection for critical equipment in HVAC installations, pumps, or process lines
• Temporary or semi-permanent installations where a durable, fusible switch provides dependable protection

What this means for your operation

The THMC31 blends reliable switching with fuse-based protection, offering a straightforward path to protect expensive motors and circuits from overloads while enabling rapid isolation for maintenance and safety. By choosing a three-pole solution, you ensure each phase is individually protected and isolated, reducing the risk of partial faults and enabling safer, cleaner disconnections during service.
