Siemens GD361 - 30A, 600V, 3-Pole, Fused Disconnect Switch

Siemens GD361 is a high‑performance fused disconnect switch engineered for safe, reliable electrical isolation in demanding industrial and commercial environments. With a 30A rating and 600V capability across 3 poles, it provides robust protection and clean disconnection under load, supporting essential lockout/tagout procedures for maintenance and safety.

Why the GD361 stands out

• Three‑pole design for complete phase isolation—ensures all conductors are reliably disconnected, reducing the risk of stray energized paths.
• Fused protection—integrated fusing adds a reliable overcurrent safeguard, helping to contain faults at the source and protect downstream equipment.
• Lockout/tagout compatibility—facilitates safe, compliant maintenance procedures by providing a clear, controllable isolation point.
• Industrial‑grade durability—built to endure busy commercial environments and the rigors of ongoing operation while maintaining consistent performance.
• Simple integration—designed to fit standard electrical assemblies where a 3‑pole, 30A, 600V fused disconnect is required.

How it works and practical benefits

The GD361 interrupts all three phases in one action, providing a definitive isolation point. In the event of an overcurrent, the fused design acts to contain the fault at the source, helping to protect downstream components and reduce arc energy. Its compatibility with lockout/tagout procedures makes it a dependable choice for routine servicing and safety compliance, while the sturdy build supports long‑term reliability in busy facilities.

Installation and maintenance tips

• Place the switch in a clearly labeled, accessible disconnect location within the electrical distribution path.
• Use appropriate lockout/tagout devices to secure the switch during maintenance and testing.
• Inspect connections for tightness and corrosion periodically, and replace fuses as specified after a fault event.
• Coordinate with your electrical schematic to ensure proper line/load orientation for safe operation.

Choose the Siemens GD361 when you need a dependable, three‑phase fused disconnect that prioritizes safe isolation, maintains performance under load, and supports rigorous maintenance practices in demanding environments.
