Westinghouse WHUN361 - 30A, 600V, 3-Pole, Fused Disconnect Switch

The Westinghouse WHUN361 fused disconnect switch is engineered for serious electrical isolation in demanding industrial and commercial settings. With a 3‑pole design and robust fused protection, it delivers dependable disconnection under load while supporting proper lockout/tagout procedures for safer maintenance and service operations.

• Amperage rating: 30A
• Voltage rating: 600V
• Number of poles: 3‑Pole
• Type: Fused Disconnect Switch
• Brand: Westinghouse
• Model: WHUN361

Why this matters: For three‑phase systems, a 3‑pole fused disconnect switch provides synchronized isolation across all hot legs, reducing the risk of arc flash and making maintenance safer and more compliant with lockout/tagout practices. The integrated fusing adds an extra layer of overcurrent protection, helping to safeguard downstream equipment, wiring, and personnel during service or fault conditions.

Key benefits and practical use

• Safe isolation under load—reliable disconnect capability even when the circuit is energized, essential for service, inspection, and troubleshooting in factories, warehouses, and plants.
• Lockout/Tagout readiness—designed to integrate with standard safety procedures, helping facilities meet workplace safety standards and regulatory requirements.
• Durable industrial build—crafted to withstand the wear and tear of busy commercial environments, delivering long‑term performance and reduced maintenance downtime.
• Versatile three‑phase protection—the 3‑pole configuration is ideal for motor drives, conveyors, HVAC equipment, and other 3‑phase systems demanding reliable isolation.

Ideal applications

• Motor control and machinery rooms requiring a dedicated disconnect with fuse protection
• Industrial conveyors, pumps, and fans in manufacturing facilities
• Commercial electrical rooms and utility spaces needing safe, code‑compliant service disconnects
