4-POLE - 400A, 4-Pole, Disconnect Switch

Meet the 4-POLE 400A Disconnect Switch—a rugged, four-pole solution engineered for industrial and commercial electrical systems that demand safe, reliable isolation. Built to support lockout/tagout procedures, this switch ensures that maintenance can proceed without risk, with independent control of each phase for complete circuit separation.

Key advantages

• Four-pole isolation provides independent breaking of all phases, ensuring no residual current can circulate during service—enhancing personnel safety and reducing arc-flash risk.
• 400A continuous rating handles high-current feeders and motors with confidence, delivering dependable disconnection under load when maintenance or emergency shutdown is required.
• Lockout/tagout compatibility is designed into the mechanism, making it straightforward to apply standard safety procedures and meet compliance in busy facilities.
• Rugged construction for harsh environments built to survive vibration, dust, and temperature variations common in industrial and commercial spaces, with durability that minimises downtime.
• Easy installation and integration optimized for panel-mounted configurations and motor control centers, streamlining retrofits and new builds alike.

Versatile use cases

Ideal for service panels, motor control centers (MCCs), main feeders, and large equipment isolations. Use it for routine maintenance on conveyors, HVAC systems, pumps, and heavy machinery, or as a primary isolation point in emergency shutdown plans. Its 4-pole design ensures full isolation even in systems with multiple live conductors.

What sets the 4-POLE apart

Unlike smaller, single-pole switches or lower-current disconnects, the 4-POLE delivers stable, long-term performance under load, reducing the chance of nuisance trips and arc accidents. Its durable construction and lockout-ready interface help you meet safety requirements without sacrificing reliability.

Operational tips

• Plan your isolation path: ensure each pole corresponds to the circuit you intend to disconnect to avoid accidental re-energization.
• Verify torque and terminal integrity during installation to maintain a solid, low-resistance connection.
• Integrate with standard lockout devices and tags to maintain compliance and worker safety during maintenance windows.
