Square D HU361DS - 30A, 3-Pole, Fused Disconnect Switch

Meet the Square D HU361DS, a robust 30A, 3-Pole Fused Disconnect Switch engineered for industrial and commercial environments that demand safe electrical isolation and dependable performance. This device blends reliable disconnection with built-in fusing to protect downstream equipment and wiring, while supporting proper lockout/tagout procedures during maintenance.

Key benefits that matter in real-world use

• Three-phase isolation: The 3-Pole design ensures all lines are safely disconnected, reducing the risk of residual energization during service or maintenance.
• 30 Amp capacity: Ideal for control circuits and moderate motor loads, delivering controlled disconnection without oversized protection.
• Integrated fusing: Fuses provide overcurrent protection at the source, helping to prevent damage from short circuits and overload events.
• Lockout/Tagout compatibility: Designed to support safe maintenance practices, allowing technicians to clearly signal a circuit is out of service.
• Durable, long-term performance: Built for reliable operation in demanding environments, reducing maintenance interruptions over time.

Practical use cases

Ideal for installation in motor control centers, switchgear assemblies, and service disconnect points where a dedicated, easily isolatable power switch is essential. It’s well-suited for industrial panels, commercial machinery rooms, and any setup requiring a clear, contained isolation point for 3-phase systems up to 30A.

Why this makes a difference

Beyond simple on/off functionality, the HU361DS provides a disciplined approach to electrical safety. The fused disconnect switch interrupts fault currents promptly, protecting both personnel during maintenance and downstream equipment from damaging transients. When paired with proper lockout/tagout procedures, it creates a safer, more predictable maintenance workflow.

Installation and fit notes

With a 3-pole configuration and 30A rating, the HU361DS is designed to integrate into standard industrial enclosures and panels used for 3-phase systems. Plan for secure mounting and compliant wiring practices to ensure reliable operation and easy access for routine testing and maintenance.

Choose the Square D HU361DS 30A 3-Pole Fused Disconnect Switch for a dependable, maintenance-friendly isolation point that enhances safety, reliability, and workflow efficiency in demanding electrical environments.
