The NEMA 3R enclosure provides weather-resistant protection, so you can rely on safe operation in outdoor or challenging environments. The fusible design means you benefit from integrated overcurrent protection at the point of use, reducing the number of separate components you must source and stock. This translates to quicker maintenance shutoffs, safer service windows, and less downtime when servicing equipment.\u003c\/p\u003e \u003ch3\u003eIdeal use cases\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eDirectly isolate critical equipment during maintenance without powering down entire systems\u003c\/li\u003e \u003cli\u003eIn panel construction and electrical assemblies where a dependable fused disconnect is required\u003c\/li\u003e \u003cli\u003eSpare inventory for service fleets to guarantee a precise, in-date part-number match\u003c\/li\u003e \u003cli\u003eOutdoor or semi-enclosed installations needing rugged weather protection and reliable disconnection\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePractical benefits and outcomes\u003c\/h3\u003e\n\u003cp\u003eWith the HF365RA, you gain a predictable, field-ready solution that simplifies compliance and safety checks. The three-pole configuration ensures coordinated disconnection across all phases, while the fusion-capable design provides overcurrent protection at the disconnect point. This minimizes fault propagation and enhances crew safety during maintenance, testing, or emergency shutdowns.\u003c\/p\u003e \u003ch3\u003eSpecifications and fit\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e HF365RA\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eType:\u003c\/strong\u003e Safety Switch (Fusible)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAmperage:\u003c\/strong\u003e 400 A\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVoltage:\u003c\/strong\u003e 600 V\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEnclosure rating:\u003c\/strong\u003e NEMA 3R\u003c\/p\u003e \u003ch3\u003eAdditional notes\u003c\/h3\u003e\n\u003cp\u003eAvailable from AmpState.
