Square D - 40A, 690V, 3-Pole, Disconnect Switch

The Square D Disconnect Switch is a purpose-built solution for safe electrical isolation in demanding industrial and commercial environments. With a 40A amperage rating and a 690V voltage rating across 3 poles, this device delivers dependable disconnection under load, helping you protect personnel and equipment during maintenance and emergencies.

• Three-pole isolation: Provides complete circuit disconnection across all conductors, ensuring a true open-circuit condition for safe servicing.
• Specified for common industrial applications: 40A and 690V ratings designed to handle typical feeders and motor circuits without compromise.
• Lockout/Tagout compatibility: Built to support standard lockout/tagout procedures, giving maintenance teams a clear, tamper-evident way to secure the line.
• Reliable under load: Engineered to perform dependable disconnections even when circuits are energized, reducing the risk of arc flash during switching operations.
• Durability for tough environments: Designed for long-term use in industrial settings, prioritizing durability and consistent performance over time.

Ideal for control panels, motor control centers, feeders, and service entrances where rapid, safe isolation is critical. The Square D disconnect switch provides a dedicated isolation point, so maintenance crews can work with confidence on de-energized equipment.

Practical considerations:

• Pair with compatible enclosures and mounting hardware typical of Square D installations for a seamless fit.
• Adhere to standard lockout/tagout procedures: lock the switch in the open position, apply a visible tag, and verify de-energization before work begins.
• Incorporate this disconnect into broader safety and maintenance plans to minimize downtime and improve response times during servicing.
