Professional Disconnect Enclosure Solutions

Fused disconnect enclosures combine switching and overcurrent protection in one unit, making them ideal for motor protection applications. Non-fused disconnect enclosures provide only switching capability and are used where overcurrent protection is provided elsewhere in the circuit, typically at a lower cost for simple isolation needs.

For standard outdoor applications, NEMA 3R provides excellent protection against rain, sleet, and ice formation. For corrosive environments near coastal areas or chemical plants, NEMA 4X with stainless steel construction offers superior corrosion resistance and additional protection against windblown dust and water.

Sizing depends on the switch amperage rating, number of poles, and space requirements for wire bending. Consider the full load current, voltage rating, and whether you need fused or non-fused protection. Our technical team can help specify the correct enclosure size based on your specific electrical requirements and installation constraints.
