GE TH3364 - 200A, 600V, 3-Pole, Heavy Duty Safety Switch

The GE TH3364 Heavy Duty Safety Switch is engineered for industrial and commercial electrical rooms where safe, reliable isolation matters most. With a 200A amperage rating and a 600V ceiling, this three-pole disconnect is purpose-built for demanding three-phase systems.

• Three-pole design provides full isolation of all conductors in 3-phase circuits, reducing the risk of accidental re-energization during maintenance.
• 200A capacity meets common feeder and motor-drive requirements without overburdening the switch, delivering dependable performance under load.
• 600V rating accommodates a wide range of industrial power applications, from manufacturing lines to large HVAC installations.
• Heavy-duty construction stands up to harsh environments, delivering long-term durability with minimal maintenance.
• Lockout/Tagout compatibility ensures maintenance crews can securely de-energize equipment, helping you stay compliant with safety standards.

Why the GE TH3364 stands out

• Reliable disconnection under load means service work can proceed with confidence when circuits are still energized, then safely de-energized for maintenance.
• Designed for industrial and commercial use, it’s ideal for service entrances, motor feeders, and equipment racks where robust safety switching is essential.
• GE’s engineering delivers consistent performance, reducing downtime and supporting safer, more efficient operations.

Ideal applications

• Manufacturing facilities with heavy electrical workloads and 3-phase motors
• Processing plants, conveyors, and large-scale HVAC systems requiring dependable isolation
• Electrical service entrances and electrical rooms where lockout/tagout procedures are standard practice

Practical tips to maximize safety and uptime

• Pair with standard lockout devices and ensure the switch is in the open position before applying LOTO to prevent accidental energization.
• Schedule periodic inspections to verify mechanical operation and keep the enclosure free of dust and debris that could impede performance in harsh environments.
• Maintain a clear, accessible indication of the switch’s status for quick, at-a-glance verification by maintenance personnel.
