Schneider Electric MD3304X - 30A, 3-Pole, Disconnect Switch

The Schneider Electric MD3304X is a purpose-built Disconnect Switch designed for demanding industrial and commercial environments where safe electrical isolation is non-negotiable. With a sturdy 3‑pole configuration and a 30A rating, it delivers dependable disconnection under load, making maintenance safer and faster while supporting rigorous lockout/tagout (LOTO) procedures.

Why the MD3304X stands out

• True 3‑phase isolation. The 3‑pole design ensures all live conductors are safely disconnected, so your three‑phase equipment is completely de‑energized during service.
• Optimized for reliability under load. Built to deliver secure disconnection even when current is flowing, reducing the risk of accidental energization during maintenance.
• LOTO‑ready safety. Specifically aligned with lockout/tagout workflows to help you meet safety standards and protect your crew during servicing.
• Durable, long‑lasting performance. Engineered for continuous use in industrial settings, standing up to daily operation and environmental stresses over time.
• Smart choice for three‑phase motor and equipment control. Ideal for panels and enclosures that service motors, pumps, fans, conveyors, and other three‑phase loads common in manufacturing and process environments.

Ideal applications

• Motor control panels and equipment enclosures requiring safe isolation for routine maintenance.
• Industrial facilities and commercial sites with three‑phase equipment duties up to 30A.
• Any work context where lockout/tagout procedures are mandatory to prevent accidental energization.

What problems this solves

• Eliminates partial energization by disconnecting all three phases, providing true shutdown of three‑phase loads.
• Supports compliant safety workflows, helping teams perform service work with clear, verifiable isolation.
• Reduces downtime and maintenance risk by offering a dependable, durable solution designed for the rigors of real‑world use.
