Square D H361NDS - 30A, 600V, 3-Pole, Fused Disconnect Switch

Engineered for durability and safety, the Square D H361NDS is a 3-pole fused disconnect switch designed to provide reliable electrical isolation in demanding industrial and commercial environments. With a 30A, 600V rating, it delivers dependable disconnection under load and supports lockout/tagout procedures to keep maintenance teams safe.

• Three-pole configuration provides balanced isolation for three‑phase systems, ensuring all live conductors can be safely disconnected.
• Integrated fusing offers immediate overcurrent protection at the disconnect point, simplifying wiring and localizing faults.
• 600V rating makes it suitable for a wide range of industrial feeders, motors, and equipment disconnects.
• Rugged, durable design built to withstand demanding environments and repeated operation, supporting long service life in real-world applications.
• Lockout/Tagout compatibility enables compliant safety procedures during maintenance, reducing the risk of accidental energization.

Ideal use cases

• Motor control and heavy machinery disconnects on manufacturing floors
• HVAC systems, pumps, and other equipment requiring reliable isolation for service work
• Primary or sub-feed disconnects in control panels and electrical distribution setups

Why this matters

Instead of a loose, unprotected switch, the Square D H361NDS consolidates fusing and disconnect functionality into a single, easier-to-manage component. This reduces wiring complexity, accelerates installation, and provides clear, verifiable protection when servicing energized equipment. It’s a pragmatic choice for facilities that prioritize safety, uptime, and code-compliant maintenance practices.
