General Electric THMS33 - 100A, 3-Pole, Disconnect Switch

When safety and uptime matter in industrial and commercial settings, the General Electric THMS33 100A, 3-Pole Disconnect Switch stands out as a purpose-built isolation solution. Engineered for reliable electrical isolation, it’s designed to support lockout/tagout procedures and deliver a clean, dependable disconnection under load. This means maintenance crews can work confidently, knowing that circuits remain dead during servicing and that re-energization is prevented until the job is complete.

Key reasons to choose the THMS33:

• 100A, 3-Pole design provides full three-phase isolation, safeguarding equipment and personnel across demanding loads.
• Lockout/Tagout compatibility supports standard safety protocols, helping facilities maintain compliance during servicing and maintenance.
• Durable, long-term performance built to withstand the rigors of busy electrical rooms and manufacturing floors.
• Straightforward installation and integration with common panel and feeder configurations for quick deployment.
• Reliable disconnection under load reduces arc risk and ensures equipment is safely isolated even when connected loads are active at the moment of opening.

Ideal use cases

• Three-phase motor circuits on assembly lines, conveyors, and machining centers.
• Service disconnects for commercial equipment and large appliance panels.
• Maintenance and diagnostic work where safe, verifiable isolation is essential.

Who benefits

• Facilities engineers, electrical contractors, and plant maintenance teams seeking a dependable, standards-aligned isolation switch.
• Businesses prioritizing safety compliance, reduced downtime, and easier lockout/tagout implementation.

Practical guidance for use

• Pair the THMS33 with your lockout/tagout procedure: apply a padlock and attach a clearly labeled tag before starting maintenance.
• Before working on equipment, verify isolation with a voltage tester to confirm absence of live energy.
• Document and secure the isolation point in your maintenance log and ensure the key is controlled by authorized personnel.
