KEA340UL - 40A, 600V, 3-Pole, Disconnect Switch

KEA340UL 3-Pole Disconnect Switch The KEA340UL is a rugged, purpose-built disconnect switch designed for industrial and commercial environments where safe electrical isolation is non-negotiable. With a three-pole configuration, it ensures complete separation of all phases in three-phase systems, providing dependable, controlled disconnection when you need it most. This model emphasizes safety, reliability, and long-term durability, making maintenance and startup procedures smoother and safer. Key specifications

• Amperage rating: 40A
• Voltage rating: 600V
• Number of poles: 3-Pole
• Product type: Disconnect Switch
• Model: KEA340UL

Why it matters for your operation

• The 3-pole design guarantees full disconnection of three-phase circuits, reducing the risk of arc flash and residual current during service or maintenance.
• Lockout/Tagout readiness: Built to support proper lockout/tagout procedures, enabling technicians to secure circuits and prevent accidental re-energization.
• Disconnection under load: Engineered to reliably interrupt power even when circuits are live, minimizing downtime and ensuring rapid, safe isolation when needed.
• Durable, long-term performance: Built to withstand the rigors of industrial and commercial environments, delivering consistent operation across years of service.

Ideal use cases

• Control panels and switchgear where a dedicated service disconnect is required
• Three-phase motor circuits, pumps, conveyors, and HVAC equipment
• Maintenance-ready disconnects in manufacturing floors, processing lines, and commercial facilities

How this differs from other options

The KEA340UL focuses on the specific needs of reliable, repeatable electrical isolation in environments where safety procedures and downtime matters. Rather than relying on fuse-based protection alone, this disconnect switch provides immediate, controllable shutdown with proper LOTO compatibility, enabling safer maintenance windows and more predictable downtime management.

Practical considerations and tips

• Plan installation in proximity to the equipment it serves to simplify lockout/tagout procedures and accessibility for maintenance
• Verify wiring and terminal connections align with your system’s conductor sizes and enclosure standards
• Pair the disconnect with appropriate lockout devices and clear tagging to enforce safety protocols during servicing
• Use as a dedicated service disconnect in three-phase circuits to maximize reliability and ease of future maintenance
