Westinghouse HU-364 - 200A, Heavy Duty Safety Switch

The Westinghouse HU-364 200A Heavy Duty Safety Switch is engineered for demanding industrial and commercial environments where safe, reliable electrical isolation is non-negotiable. It delivers dependable disconnection under load and supports proper lockout/tagout procedures, helping teams maintain safe, compliant operation even on busy maintenance days.

• 200 Ampere rating provides robust protection for large equipment, motor circuits, and distribution panels, enabling safe isolation without compromising performance.
• Heavy duty construction built for long-term durability in challenging environments, reducing the need for frequent replacements and downtime.
• Safe electrical isolation ensures a clear, reliable disconnect so maintenance can proceed with confidence and reduced risk.
• Lockout/tagout readiness designed to integrate with standard safety protocols, helping facilities stay compliant during servicing and audits.
• Reliable disconnection under load maintains system safety even when circuits are energized, supporting safer commissioning and de-energizing procedures.

Ideal for: facilities and sites that require dependable switchgear for routine power distribution, equipment shutoffs, and service disconnects—industrial plants, commercial buildings, and any operation with heavy electrical loads that demand strict safety controls.

Use cases and practical scenarios:

• Disabling power to large motors or heavy machinery for maintenance without exposing technicians to live circuits.
• Serving as a primary service disconnect or as a dedicated feeder disconnect within motor control centers and switchgear assemblies.
• Implementing lockout/tagout procedures during routine servicing to ensure readiness and compliance during audits.

What sets the Westinghouse HU-364 apart is its combination of high-current capability, proven durability, and safety-focused features that align with real-world maintenance workflows. Unlike lighter-duty switches, the HU-364 is purpose-built to withstand industrial use cycles while delivering a dependable, clearly isolated disconnect when it matters most.
