Westinghouse JHU362 - 60A, 600V, Heavy Duty Fused Disconnect Switch

Introducing the Westinghouse JHU362 Heavy Duty Fused Disconnect Switch — a purpose-built isolation device for demanding industrial and commercial environments. With a 60A rating and a 600V maximum, this disconnect delivers dependable electrical isolation where safety and reliability are non-negotiable. It supports proper lockout/tagout procedures, enabling technicians to work confidently on energized equipment while preventing accidental re-energization.

Why the JHU362 stands out

• Solid 60A/600V capability. Engineered to handle feeder circuits, motors, and control panels, the JHU362 provides appropriate protection for a wide range of applications in industrial facilities and commercial settings.
• Integrated safety through fusing. The heavy-duty fused design delivers overcurrent protection for the circuit, helping to minimize fault propagation and protect downstream gear during startup, operation, and maintenance.
• Lockout/tagout compatibility. The switch is designed to support lockout/tagout practices, allowing technicians to apply padlocks and tags for safe servicing and compliant shutdowns.
• Reliability under load. Built for frequent operation in tough environments, the JHU362 delivers a clear, reliable disconnection when it’s needed most, protecting personnel and equipment at the point of isolation.
• Flexible integration. Designed to fit into service disconnect points, switchgear, and control panels, the JHU362 eases installation in existing layouts without sacrificing performance.
