GE THMS31 - 30A, 3-Pole, Disconnect Switch

The GE THMS31 is a purpose-built 30A, 3-Pole Disconnect Switch designed for industrial and commercial environments where safe electrical isolation is non-negotiable. It delivers dependable disconnection under load while supporting robust lockout/tagout procedures, helping to keep maintenance crews safe and downtime minimal.

What sets the THMS31 apart is its focused, three-phase isolation capability combined with durable performance. The 3-pole configuration ensures balanced isolation for three-phase equipment, so motors and other three-phase loads can be safely shut down without partial energization. The 30-amp rating covers a wide range of common industrial applications, from small motors to control circuits, providing reliable protection during service or repair work. Built for long-term use, this disconnect switch maintains consistent operation in demanding environments where reliability matters most.

Ideal use scenarios include:

• Isolating three-phase motors on manufacturing lines for safe maintenance
• Isolating HVAC equipment and large processing systems during servicing
• Providing a clear, code-compliant shutdown point in control panels and electrical enclosures
• Serving as a dedicated disconnect for temporary power during equipment upgrades or testing

Why this matters for you: with the GE THMS31, you get a dedicated, reliable means of de-energizing equipment exactly where you need it, reducing the risk of accidental re-energization and speeding up service workflows. Its straightforward design supports consistent, repeatable lockout/tagout practices, which translates to safer work environments and clearer maintenance procedures.
