Key advantages that matter in the field

• Robust NEMA 3R enclosure designed for outdoor installations and damp environments without compromising safety
• 800 Ampere capacity with 3 poles, engineered to interrupt large feeders and safeguard downstream equipment
• 600V maximum system voltage support, aligning with common industrial power distribution needs
• Fusible or non-fusible configurations—choose the protection and isolation level that fits your system design
• Consistent part number for retrofit projects, reducing downtime spent hunting for replacements
• Backed by Square D, a trusted name in safety and control solutions

Practical use cases

Ideal for plant upgrades, service disconnects at machine or line feeders, and maintenance work requiring a quick, safe shutdown. The HU367R is well-suited for retrofit scenarios where your existing electrical layout relies on a fixed part number to keep spares aligned with your maintenance calendar. Use in outdoor enclosures, on trailer or skid-mounted power distributions, and any application needing a reliable, code-compliant disconnect switch.

What makes it different from generic switches

Unlike bare disconnects, the HU367R emphasizes safety and serviceability. The NEMA 3R rating protects against weather exposure, while the 800A rating provides headroom for motor loads and feeders. The dual configuration (fusible/non-fusible) offers design flexibility without swapping components in your panel or system.
