Siemens LBT4040 - 40A, 4-Pole, Disconnect Switch

Siemens LBT4040 is a 40A, 4-Pole Disconnect Switch built for harsh industrial and commercial environments where safe, reliable electrical isolation is non-negotiable. This unit delivers dependable disconnection under load, making maintenance safer and downtime more predictable, while supporting proper lockout/tagout procedures to keep personnel protected during service.

Why this 4-Pole disconnect stands out

• Complete conductors isolation in one action: The 4-pole configuration simultaneously disconnects four conductors, reducing arc exposure and simplifying safe stoppage of energized circuits.
• Solid 40A performance: Designed for mid-range loads common in control panels, motor circuits, and feeder lines, delivering consistent operation without compromise.
• Lockout/tagout ready: Built to support standard lockout/tagout workflows, helping you maintain compliance and protect technicians during servicing.
• Engineered for durability: Constructed for long-term service in demanding environments, with robust mechanical action that resists wear over time.

Ideal applications

• Industrial control panels and motor control centers requiring safe feeder disconnection.
• Commercial facilities where equipment must be isolated before maintenance or repair work.
• Emergency isolation points to quickly de-energize circuits during troubleshooting.
