Square D HU361AWK 30A 3P 600V Safety Switch, NEMA 3R, Fusible, Non-Fusible | AmpState

The Square D HU361AWK 30A 3P 600V safety switch is a purpose-built equipment disconnect and isolation device designed for reliable performance at the point of use. With a rugged NEMA 3R enclosure, this switch stands up to outdoor and challenging industrial environments, delivering safe, straightforward shutdown when it matters most. Available in both Fusible and Non-Fusible configurations, it offers flexible protection options to align with your maintenance strategy.

• Direct part-number match: A smart pick for maintenance teams, panel builders, and spare inventory where compatibility matters and fast ordering saves time.
• Fusible or Non-Fusible configuration: Choose the protection mode that suits your system design—fusing integrated into the disconnect, or a simple, dependable non-fusing disconnect for easy servicing.
• NEMA 3R enclosure: Weather-resistant and durable, ideal for outdoor installations and damp environments without compromising safety.
• Three-pole, 600V rating: Handles higher voltage circuits with robust isolation, suitable for motors, pumps, conveyors, and other demanding loads.
• Point-of-use isolation: Quick, safe electrical shutdown right at the equipment you’re servicing, reducing downtime and improving maintenance efficiency.

Ideal use scenarios include outdoor or semi-outdoor motor and load disconnects, panel builds that require a precise part-number match, and maintenance workflows where a reliable, accessible shutoff is essential. The HU361AWK is designed to integrate seamlessly into existing gear while giving you the flexibility to adapt protection as your system evolves.

How to decide between Fusible and Non-Fusible: If your protection scheme relies on built-in fusing, select the Fusible configuration. If you need a straightforward disconnect without built-in fuses, the Non-Fusible variant provides a clean, maintainable option. Both share the same form factor for straightforward replacement or future upgrades.
