Square D H361N - 30A, 600V, 3-Pole, Fused Disconnect Switch

The Square D H361N 3-Pole Fused Disconnect Switch delivers reliable, lockable electrical isolation for demanding industrial and commercial environments. With a 30A rating and a 600V capacity, this fused disconnect is built to protect people and equipment while enabling safe maintenance and service operations. Designed to support proper lockout/tagout procedures, it provides a dependable disconnect under load, helping you minimize downtime and maximize system uptime.

Why this model stands out

• Fused protection for safer isolation. Combines a disconnect with integral fusing to guard circuits against overloads, so maintenance teams can work confidently without exposing equipment to uncontrolled faults.
• 3-pole configuration for three‑phase systems. Specifically suited for standard 3-phase motors and equipment, ensuring consistent, balanced isolation across all live conductors.
• Lockout/tagout readiness. Built to accommodate padlocks and clear labeling, supporting compliant energy control procedures and personnel safety during servicing.
• Durable, field-ready design. Engineered for long-term durability in harsh environments, with a robust mechanism that maintains performance through frequent operation and vibration common in industrial settings.
• Easy integration. Designed to fit alongside standard control panels and enclosures, making retrofits and new installations straightforward without complicated wiring changes.

Ideal applications

• Motor control circuits for conveyors, pumps, and fans where a safe servicing disconnect is required
• Secondary shutdowns in production lines and processing equipment
• Maintenance shutoffs for industrial machinery and operation-critical panels
• Service disconnects in commercial and light industrial electrical rooms

How it helps you operate safely and efficiently

When equipment needs maintenance or repair, the H361N provides a clearly isolated, lockable off state while the rest of the system remains protected by fuse protection. The 3-pole design ensures all live conductors are simultaneously disconnected, reducing arc flash risk and allowing technicians to work in a controlled, de-energized environment. Its durable construction stands up to daily use in demanding facilities, helping keep downtime to a minimum and performance consistent over the life of your installation.
