Cutler-Hammer HD361N - 30A, 600V, 3-Phase, Fusible, Switch

Meet the Cutler-Hammer HD361N — a compact, maintainable fusible switch engineered for demanding industrial and commercial environments. With a 30A, 600V rating across 3 phases, this unit delivers reliable on/off isolation while providing steady overcurrent protection for motors and critical equipment. It’s the practical choice when you need a dedicated motor disconnect or a dependable branch-circuit protector in a single, rugged package.

Why the HD361N stands out

• Three-phase, 30A at 600V: designed to handle multi-motor and multi-load circuits with balanced protection across all lines.
• Fusible protection: integrated fuses interrupt faults quickly, reducing stress on downstream components and improving system safety.
• Compact, maintainable design: a smaller footprint without sacrificing reliability, making it ideal for panelboards and tight spaces.
• Versatile isolation: provides clear, local disconnect for routine maintenance and emergency shutdowns in busy facilities.
• Rugged for industrial use: built to perform in harsh environments where dependable power control matters most.

Ideal applications

• Motor disconnects on conveyors, pumps, fans, and compressors within manufacturing and processing plants.
• Protection and control points in panelboards where a compact, fusible switch is preferred over larger disconnect solutions.
• Branch circuit protection for equipment suites in warehouses, data centers, and large mechanical rooms.

What this means for you

The HD361N offers a straightforward path to reliable electrical protection without sacrificing ease of maintenance. By combining a robust on/off switch with fusible protection, it simplifies wiring, reduces downtime during fuse changes, and provides a clear isolation point for safety checks and servicing. If your goal is to safeguard motors and sensitive equipment while keeping installation tidy and serviceable, this Cutler-Hammer solution is purpose-built for that mission.

Practical tips for use and upkeep

• Match the fuses to the HD361N’s specified ratings to ensure the intended protection without nuisance tripping.
• Always de-energize the circuit and follow lockout/tagout procedures before performing fuse replacement or servicing.
• Store common fuse types on-site to minimize downtime during routine maintenance or fault conditions.
• Use in applications where a dedicated switch for motor protection improves electrical safety and allows quick isolation for troubleshooting.
