Square D HU361 - 30A, 600V, 3-Pole, Heavy Duty Non-Fusible Safety Switch

When safety and reliability matter most in demanding industrial and commercial environments, the Square D HU361 delivers robust, dependable circuit isolation. This 30A, 600V Heavy Duty Non-Fusible Safety Switch is engineered to provide a clear, decisive disconnect under load, supporting safe maintenance and operational continuity.

• 30A at 600V – Ideal for medium-duty, three-phase electrical systems that require a solid, trusted disconnect.
• 3-Pole configuration – Designed to reliably interrupt all three phases, ensuring complete isolation of three-phase circuits.
• Heavy Duty Non-Fusible design – A rugged safety switch that provides a clean, fuse-free disconnect, leaving protection coordination to the appropriate external devices.
• Safe lockout/tagout compatibility – Supports proper lockout/tagout procedures, helping technicians perform maintenance without energizing equipment.
• Disconnection under load – Built to interrupt power safely even when circuits are energized, reducing the risk of unexpected energization during servicing.
• Industrial-grade durability – Constructed to withstand the rigors of demanding environments, delivering reliable performance over time.

Ideal for machine control panels, service disconnects, and area isolation within electrical rooms, the HU361 equips you with a trustworthy solution when clean, immediate power isolation is non-negotiable. It’s a practical choice for facilities that require straightforward, dependable electrical safety without fusible elements.

Why choose the HU361? It prioritizes practical safety and consistent performance in everyday operations. You’ll appreciate its clear, immediate disconnect capability, which helps minimize downtime during maintenance and supports compliance with lockout/tagout procedures. For engineers and technicians responsible for reliable electrical safety, this switch offers a concrete, field-proven option that aligns with real-world needs.

Practical tips: pair the HU361 with compatible enclosures and standard panel work to create a streamlined safety disconnect point. Ensure your system’s protection strategy matches the non-fusible approach, using external fusing or breakers as appropriate for your application. Regular inspection of mounting integrity and terminal connections will help maintain optimal performance and long service life.
