GE THN3361R - 30A, 3-Pole, Non-Fusible Disconnect Switch

Engineered for reliability in demanding industrial and commercial environments, the GE THN3361R 30A, 3-Pole Non-Fusible Disconnect Switch delivers confident electrical isolation when it matters most. Designed to work with proper lockout/tagout procedures, this switch provides a clear, local disconnect for quick, safe maintenance and service.

• Three-pole isolation: Disconnects all three conductors in a three-phase system, delivering full, dependable disconnection for safer maintenance and protection of personnel.
• Non-fusible design: No built-in fuse means you pair the disconnect with the appropriate external protection devices, enabling flexible system protection while keeping the disconnection point simple and accessible.
• Lockout/Tagout friendly: Built to support standard lockout/tagout procedures, helping you clearly control energy sources during service and reducing downtime risk.
• Industrial-grade durability: Built to endure the rigors of continuous use in busy facilities, with a focus on long-term reliability and consistent performance under load.
• Clear, immediate isolation under load: Designed to provide a reliable disconnection even when downstream equipment is energized, minimizing exposure and enabling safer intervention.
• Straightforward installation and integration: This switch fits into common electrical workflows and enclosures, simplifying routing, wiring, and future maintenance tasks.

Who benefits most: electrical contractors, facilities managers, maintenance technicians, and plant engineers who need a dependable, easy-to-control means of isolating three-phase circuits. If your operation relies on predictable shutdowns for motor controls, HVAC systems, or line feeders, the THN3361R helps you meet safety standards without complicating your protection scheme.
