1494V-DH611 - 100A, 1494V, Fused Disconnect Switch

The 1494V-DH611 is a high-performance fused disconnect switch engineered for demanding industrial and commercial environments that demand safe, reliable electrical isolation. With a 100A rating and a 1494V capacity, this switch provides dependable, on-demand disconnection to support maintenance, testing, and routine servicing without sacrificing safety or system uptime.

Why choose a fused disconnect like the 1494V-DH611? Unlike simple disconnects, the fusion element adds protective separation for circuits, helping to guard downstream equipment from fault conditions while you lock out and tag out for service. This design enables precise, controlled isolation even when the circuit is energized, reducing arc exposure and helping you meet safety procedures on large feeders and high-voltage lines.

Key features and benefits

• 100A current rating at 1494V—handles substantial high-voltage circuits typical in industrial power distribution and large equipment feeds.
• Integrated fuse protection—provides overcurrent protection in the same assembly, simplifying wiring and maintenance planning.
• Lockout/Tagout (LOTO) compatibility—designed to support proper energy-isolation procedures so maintenance teams can work safely.
• Reliable disconnection under load—engineered to interrupt circuits cleanly, helping minimize downtime and arc exposure during service or testing.
• Durable, long-lasting construction—built to endure industrial environments where reliability and robust performance are essential day after day.

Ideal applications

• Industrial power distribution panels and motor feeders where high-voltage isolation is required
• Commercial facilities with critical equipment that must be safely isolated for maintenance
• System commissioning, testing, and startup sequences where quick, safe isolation is needed
• Area where strict lockout/tagout compliance is part of daily operations

How it helps you operate smarter

• Eliminates the need to source separate fuses and disconnects for certain circuits, reducing component count and installation time.
• Facilitates safer maintenance workflows by enabling secure, documented isolation of live circuits.
• Supports longevity and reliability of downstream equipment by preventing uncontrolled fault conditions from propagating.

Care, installation, and reliability tips

• Match the fuse rating to your specific circuit and cable sizing to maintain optimal protection.
• Ensure proper mechanical installation to maintain ease of operation and reliable disconnection when needed.
• Schedule regular inspections for signs of wear, corrosion, or damage to the enclosure and connections, and replace fuses promptly when blown.
• Document lockout/tagout procedures and train personnel so maintenance teams can consistently follow safe-energy isolation practices.
