FAQs
DH323URKA1240 is designed for a NEMA 3R enclosure and uses a three-pole, three-wire configuration suitable for surface or panel mounting in industrial environments. Its 16 in depth, 24.93 in height, and 26.58 in width dimensions, combined with a 108 lb weight, indicate a rugged, non-fusible main-disconnect solution that fits standard control panels while withstanding outdoor or dusty conditions.
The device is rated for 100A and 240 VAC, configured as non-fusible with three poles and three wires. This means it provides a reliable, non-fused disconnect suitable for main-line control in 240 VAC circuits, while delivering safe isolation without internal fusing. It is UL Listed for added assurance.
Ideal for heavy-duty industrial panels, process automation, and outdoor equipment enclosures where a robust, non-fusible main switch is needed. The NEMA 3R enclosure and galvanized steel construction support environments with exposure to moisture, dust, and varying temperatures, common in manufacturing, water treatment, and material handling.
DH323URKA1240 is UL Listed, confirming compliance with safety standards for electrical equipment. The NEMA 3R enclosure rating further ensures protection from rain, sleet, and external objects. These certifications streamline regulatory approvals and periodic audits for industrial facilities, reducing risk during inspections.
With a one-year warranty from installation (or 18 months from shipment) and durable galvanized steel construction, this switch minimizes maintenance frequency and downtime. The heavy-duty build supports long service life in challenging environments, lowering replacement costs and simplifying spare-part planning for facilities with high uptime requirements.
