• Model: WHU-361
• Amperage: 30A
• Voltage: 600V

Why the WHU-361 matters

In facilities where uptime and safety are non-negotiable, a dedicated safety switch is essential. The WHU-361 provides clear, mechanical isolation to safely disconnect power, while its built-in protection helps prevent damage from overcurrent conditions. Its compact footprint makes it suitable for crowded panelboards and tight electrical rooms, reducing installation complexity without compromising performance.

Key use cases

• Motor disconnects in manufacturing lines or processing equipment, enabling safe maintenance and service.
• Panelboard protection where a compact, reliable switch is required to isolate circuits quickly.
• Branch circuit protection in commercial spaces, ensuring fast, clean power interruption during faults.

Unique advantages you’ll notice

• Compact, maintainable design fits into tight spaces and simplifies inspection, testing, and replacement of fusible components.
• Dedicated isolation with overcurrent protection reduces risk of electrical faults propagating through your system.
• Industrial-grade reliability engineered for environments where continuous operation and quick, safe power shutoff matter most.
• Versatile integration complements cabinetry, motor control centers, and distribution panels without extensive rework.

Installation and practical considerations

Plan for straightforward wiring and secure mounting within standard enclosures. Ensure compatibility with your panelboard or switchgear configuration and follow local electrical codes for safe connection, labeling, and testing. Regular visual inspections and periodic performance checks will help maintain reliable isolation and protection over time.

Who this is ideal for

Facilities managers, maintenance teams, and electrical contractors seeking a proven, compact safety switch for motor disconnects, panelboard protection, and branch circuits in industrial and commercial settings. If you need a dependable, easy-to-service solution that pairs isolation with overcurrent protection, the WHU-361 is a strong fit.

How it compares to a basic disconnect

Unlike simple disconnects that solely interrupt power, the WHU-361 combines reliable isolation with built-in overcurrent protection in a single, maintainable unit. This fusion simplifies wiring, reduces component counts, and supports safer, more efficient maintenance and fault handling without sacrificing performance.
