Square D CH361AWC - 30A, 600V, 4-Pole, Heavy Duty Fused Disconnect Switch

Meet the Square D CH361AWC—a purpose-built, Heavy Duty Fused Disconnect Switch engineered for demanding industrial and commercial environments. With a 30A amperage rating and a 600V capacity, this 4-Pole disconnect delivers safe, reliable electrical isolation when it matters most. Built to support proper lockout/tagout procedures, it ensures maintenance and servicing can proceed without compromising operator safety, while providing dependable disconnection under load for long-term durability.

Why engineers choose the CH361AWC

• Four-Pole isolation: Fully disconnects all conductors in multi‑phase systems to prevent arcing and ensure complete de-energization during service or maintenance.
• Heavy‑duty fused protection: Integrated fusing adds an extra layer of overcurrent protection, reducing electrical stress on downstream equipment and simplifying fault response.
• Wide voltage readiness: Rated for up to 600V, making it suitable for a broad range of industrial power layouts and control circuits.
• Compact reliability: Rugged construction designed to withstand harsh environments while delivering consistent performance over time.
• Lockout/Tagout compatible: Built with safety procedures in mind, enabling secure control of energy sources during maintenance or shutdowns.
• Clear, decisive disconnection under load: Fast and reliable switching behavior minimizes downtime and protects both personnel and equipment.

Ideal applications and use cases

• Motor control centers and process lines in manufacturing facilities that demand dependable isolation and quick serviceability.
• Commercial and industrial electrical panels where a robust power disconnect is required for routine maintenance and safety compliance.
• HVAC, water treatment, and other utility systems that benefit from a dedicated, easily serviceable disconnect switch.
• Emergency shutdown and routine lockout/tagout scenarios where a secure, clearly identifiable disconnect point is essential.
