Siemens 3POLE - 100A, 240V, 3-Pole, Disconnect Switch

Introducing the Siemens 3POLE 100A, 240V three-pole Disconnect Switch — a purpose-built solution for safe, reliable electrical isolation in industrial and commercial environments. Designed to withstand demanding duty, this switch supports proper lockout/tagout procedures and delivers dependable disconnection under load, keeping personnel and equipment protected during maintenance and service work.

Key advantages of the Siemens 3POLE Disconnect Switch

• Three-pole isolation provides full-phase control, ensuring every live conductor is safely disconnected when you need it most.
• 100A at 240V rating ideal for feeders, distribution panels, and motor circuits in mid-size facilities.
• Lockout/Tagout readiness designed to integrate with standard LOTO devices, helping you maintain safe maintenance procedures.
• Under-load disconnection capability minimizes risk when switching off equipment still energized, reducing arc and equipment wear.
• Durable, long-lasting construction built to endure harsh industrial environments, delivering reliable performance over time.
• Seamless integration with Siemens electrical systems and existing panels, simplifying replacement or upgrades without custom adapters.

Ideal use cases

Use the Siemens 3POLE in main service disconnect points for commercial buildings or manufacturing floors, at motor control centers, or in feeder applications where full isolation is required before maintenance. It also serves as a trusted emergency shutoff in production lines and HVAC or processing equipment, providing maintenance teams with a clear, reliable disconnect path.

What makes it unique

Unlike simpler single-pole devices, the 3POLE delivers true three-phase isolation, reducing the risk of backfeed and ensuring equipment cannot be energized while being serviced. The combination of a robust 100A/240V specification with lockout/tagout compatibility makes it a practical, safety-forward upgrade for facilities aiming to enhance electrical safety and reliability.
