General Electric | TH3365SS | Disconnect Switch | 400A | 3-Pole | 600V

General Electric TH3365SS Disconnect Switch is built to deliver reliable electrical isolation in demanding industrial settings. With a 400A rating across 3 poles and a 600V maximum operating voltage, this switch is designed to safely disconnect large feeders and motor circuits for maintenance, retrofit, or replacement projects. The TH3365SS part number serves as the clearest reference for compatibility with GE equipment and existing switchgear.

• Amperage: 400A
• Pole configuration: 3-Pole (three-phase)
• Voltage rating: 600V
• Reference: TH3365SS for compatibility alignment
• Primary use: maintenance isolation, system retrofits, and component replacement

The 3-Pole design ensures simultaneous isolation of all three current-carrying lines, providing true three-phase safety during servicing. This makes it especially valuable in environments where uninterrupted uptime matters but essential service requires a reliable shutdown path — from manufacturing floors and motor control centers to large facility distribution panels.

Why choose the TH3365SS for your project

• Dedicated GE part number for precise compatibility with GE panels and control gear, reducing the risk of mismatches during retrofits or replacements.
• Clear demarcation of ratings (400A, 3-Pole, 600V) helps you match the switch to your existing distribution topology and feeder requirements.
• Designed to be integrated into maintenance routines, enabling technicians to isolate circuits quickly and confidently without compromising safety margins.

Ideal use cases

• Retrofits and upgrades of aging switchgear where a compatible GE disconnect is required to maintain system integrity.
• Maintenance shutdowns for large motors, feeders, and three-phase power distribution on industrial plants.
• Replacement of failing disconnects in service panels and motor control centers where 3-pole, 600V operation is standard.

Practical tips for installation and procurement

• Always confirm fit and ratings before ordering, using TH3365SS as the definitive compatibility reference.
• Match the switch’s amperage, pole count, and voltage rating to your current electrical layout to ensure seamless integration.
• Have a licensed electrician perform installation and verification to maintain system safety and compliance with your facility’s electrical standards.
• Keep documentation handy with the part number TH3365SS for future replacements or maintenance planning.

For projects requiring a dependable, industrial-grade isolator that aligns with GE equipment, the General Electric TH3365SS Disconnect Switch delivers clear, practical value. It’s tailored for maintenance, retrofit, and replacement scenarios where precise compatibility and robust performance matter most.
