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

Meet the Square D HU361DS, a compact 30A, 600V, 3-Pole Fusible Disconnect Switch designed for reliable on/off isolation and overcurrent protection in demanding industrial and commercial environments. This unit combines trusted Square D reliability with a design that fits tight spaces where quick service and straightforward maintenance matter.

The HU361DS is a fusible disconnect switch, providing inherent overcurrent protection for circuits and motors. Its 3-pole configuration ensures full isolation of all conductors, improving safety during maintenance and servicing. The fusible design means protection is integrated into the switch assembly, reducing the need for separate protective devices and simplifying wiring in panelboards and switchgear.

Key features and benefits

• Three-pole isolation: complete disconnection of all conductors for safe maintenance and clear shutoff in one unit.
• Fusible protection: integrated overcurrent protection that responds quickly to overloads or faults.
• Industrial-ready durability: built to withstand demanding environments in manufacturing, facilities, and large commercial applications.
• Compact, maintainable design: optimized for space-constrained installations with serviceability in mind.
• Motor disconnect and panel protection: ideal for motor disconnects, panelboards, and branch circuit protection where a compact solution is required.
• Voltage rating up to 600V: suitable for a wide range of industrial power distribution needs.

Use cases and installation scenarios

Common applications include motor control centers where a dedicated shutoff is required, panelboards needing a reliable disconnect, and branch circuits that demand both isolation and protection in a single assembly. Whether you're building a new facility, upgrading a distribution panel, or performing maintenance on existing equipment, the HU361DS delivers straightforward integration with your electrical infrastructure.

Why this matters for your operation

With a Square D HU361DS in your electrical lineup, you gain:

• Faster maintenance planning thanks to true active isolation from a single switch.
• Enhanced safety from a clearly defined disconnect point in the circuit path.
• Reduced wiring complexity by combining switching and protection in one device.
