Why the HU-363 matters for your operation

• Safe electrical isolation for maintenance: Clear, reliable isolation ensures technicians can service equipment with confidence and reduced risk.
• Lockout/tagout readiness: Specifically suited to implement lockout/tagout procedures, helping protect personnel during servicing and inspections.
• Dependable disconnection under load: Engineered for reliable operation when switching under load, contributing to equipment protection and downtime minimization.
• 100A rated performance: Appropriate for mid-size feeders and distribution paths common in industrial and commercial facilities.
• Rugged, durable build: Designed to withstand the rigors of harsh environments typical in warehouses, manufacturing floors, and utility rooms.
• Long-term reliability: Built for longevity with components chosen to endure frequent operation and seasonal demand without compromising safety.

Ideal applications

Use the Westinghouse HU-363 in spaces where controlled power shutdown is essential: equipment rooms, service panels, motor control centers, and main distribution panels in factories, manufacturing facilities, large commercial buildings, and other environments where predictable isolation is critical for maintenance and safety. It’s especially valuable where adherence to lockout/tagout protocols is a priority and where operators need a trustworthy, immediate means to disconnect power.

What sets this safety switch apart

Beyond its basic function, the HU-363 emphasizes practical safety and reliability. Its 100A rating aligns with common industrial circuits while the heavy‑duty design resists wear from frequent switching and environmental exposure. This isn’t a generic safety switch—it’s a purpose-built solution intended to integrate smoothly with standard electrical rooms and maintenance workflows, helping facilities meet safety standards and minimize unscheduled downtime.

Usage and best practices

• Integrate with your lockout/tagout program: Pair the switch with approved hasps and tags to ensure authorized personnel control energy during servicing.
• Plan for routine checks: Periodically verify switch contacts and integrity of the mounting and enclosure to sustain safe operation over time.
• Coordinate with maintenance schedules: Use the HU-363 to create clear, auditable shutdown points for complex equipment outages and preventive maintenance.
