Square D H361DSWC - 30A, 600V, 3-Pole, Fused Disconnect Switch

The Square D H361DSWC is a rugged, 3-pole fused disconnect switch built for reliable electrical isolation in demanding industrial and commercial environments. With a 30A rating and a 600V capacity, this unit delivers dependable disconnection under load and is designed to integrate seamlessly with standard lockout/tagout (LOTO) procedures, keeping maintenance teams safe during service.

Why this switch stands out

• Fused protection for added safety: The integrated fuses provide overcurrent protection, helping shield downstream equipment and wiring from faults while enabling a clean, definitive disconnect when needed.
• Three-pole design for complete isolation: All three phases are simultaneously opened, reducing arc risk and ensuring a true electrical break during maintenance or emergencies.
• Lockout/tagout compatibility: The H361DSWC is engineered to support standard LOTO practices, allowing technicians to secure the circuit in the OFF position and work safely without accidental energization.
• Built for durability: Intended for continuous operation in challenging environments, this switch balances sturdy construction with reliable performance over time.
• Clear applicability for industrial circuits: Ideal for panel disconnections, motor drives, and equipment where reliable isolation is essential for safe service and downtime reduction.
• Reliable under load: Designed to maintain a dependable disconnect even when circuits are energized, helping minimize risk during switching operations.
