Why choose the H361AWK for your electrical safety strategy

• Integrated overcurrent protection with safe isolation. The fused design reduces the risk of arc flash and provides protective coordination for downstream equipment, so maintenance teams can work with the circuit isolated.
• Three-pole coverage for balanced 3-phase systems. By interrupting all three hot legs, it guarantees complete isolation of the circuit, preventing partial power exposure during servicing.
• Reliability you can depend on. Built for long-term durability in environments that demand consistent performance, even with frequent use and load changes.
• Lockout/tagout readiness. Designed to integrate smoothly with standard lockout/tagout practices, helping you meet safety compliance during maintenance and inspections.
• Versatile installation. Suitable for mounting in a variety of industrial control configurations, from panelboards to standalone enclosures, where a robust fused disconnect is required.

Ideal use cases

• Motor feeders and drive circuits in manufacturing lines, conveyors, and pumps where reliable isolation is critical for service work.
• HVAC and automated equipment where a quick, safe disconnect protects technicians during routine maintenance.
• Control panels and switchgear assemblies requiring a durable fused safety switch to meet locking and tagging procedures.

What problems this solves

• Eliminates ambiguity during maintenance by providing a clear, fully isolated point of disconnect that can be locked out.
• Reduces downtime and calibration risk by ensuring a secure, load-rated disconnection instead of relying on uncontrolled power down.
• Improves personnel safety with dependable isolation across all three phases, minimizing exposure to energized circuits during servicing.

Practical tips for best results

• Pair the H361AWK with compatible lockout/tagout devices and tag-out kits to streamline compliance during maintenance windows.
• Verify circuit load and compatibility with a 30 A, 600 V rating before installation to ensure optimal performance.
• Schedule periodic fuse inspections and replacement with identical rating fuses to maintain protective integrity and safe operation.
• Document the location and wiring configuration within your electrical drawings to simplify future servicing and safety checks.
