Square D HU361DS - 30A, 600V, 3-Pole, Non-Fusible Disconnect Switch

Introducing the Square D HU361DS—30A, 600V, 3-Pole, Non-Fusible Disconnect Switch—designed to deliver safe, reliable electrical isolation in demanding industrial and commercial environments. This non-fusible disconnect switch provides a straightforward, durable solution for safeguarding maintenance work and ensuring accurate off-stage isolation when power must be isolated.

Key advantages that matter in real-world operations:

• Three-pole isolation ensures complete disconnection of all conductors in three-phase systems, reducing the risk of arc flash or unintended energization during servicing.
• Non-fusible design offers robust mechanical operation without the complexity of fused elements, simplifying routine maintenance and replacement workflows.
• 30A at 600V supports a wide range of control circuits, motors, pumps, conveyors, and other commercial/industrial equipment without overloading the switch.
• Lockout/tagout ready compatibility helps you enforce safe maintenance practices by preventing accidental re-energization during service.
• Built for durability engineered to withstand the rigors of busy facilities, providing dependable performance over the long term.

Ideal applications

• Machine isolation on manufacturing lines and assembly benches
• Motor control centers and equipment where safe shutdown is essential
• HVAC systems, pumps, and conveyors in commercial or light industrial spaces
• Service entrances and panel isolation points where a clear, immediate disconnect is required

Why this matters in your operations

When maintenance or repair is needed, accurate and reliable electrical isolation is non-negotiable. The HU361DS provides a clear, mechanical disconnect that you can count on under load, reducing downtime and improving safety. By choosing a dedicated non-fusible disconnect switch, you avoid the complexity of fuse-based protection where you simply need a reliable isolation point to perform safe work.
