Cutler-Hammer FDT3622 - Fusible, Switch

Introducing the Cutler-Hammer FDT3622 Fusible Switch — a compact, rugged disconnect designed for reliable on/off isolation and immediate overcurrent protection in demanding industrial and commercial environments. Built to endure heavy-duty duty cycles, this switch helps keep critical equipment safe and uptime high.

Model: FDT3622 • Fusible by design, delivering integrated protection for circuits where quick interruption of fault current matters most. This makes it an ideal choice for motor disconnects, panelboards, and branch circuit protection, all in a footprint that fits tighter enclosures and spaces.

Key advantages that matter in the field

• Fusible protection provides fast fault interruption, helping prevent damage to downstream equipment and enabling coordinated response with other protective devices.
• Compact, maintainable design reduces installation complexity and enclosure depth while simplifying routine service and fuse replacement.
• Reliable isolation enables safe maintenance and clear de-energization of circuits with confidence.
• Versatile application specifically suited for motor disconnects, panelboards, and branch circuits in both industrial facilities and commercial buildings.
• Durable performance engineered to withstand the rigors of demanding electrical environments, preserving safety and reliability over time.

Practical use cases

• Install as a motor disconnect in manufacturing lines, providing a safe, code-compliant means to isolate power for servicing equipment.
• Use as a main or sub-disconnect in panelboards to manage power distribution with integrated overcurrent protection.
• Implement on branch circuits to shield downstream devices from overload while maintaining a compact footprint in control panels.
• Employ in systems requiring straightforward maintenance—fuses can be replaced quickly to minimize downtime.

Who benefits most

Maintenance teams, electrical engineers, and facility managers in industrial settings, processing plants, and commercial facilities where space is at a premium and reliable isolation plus protection is essential.

With the Cutler-Hammer FDT3622 Fusible Switch, you get a purpose-built solution that combines the convenience of a switch with the safety of integrated fusing—delivering clear advantages over broader, non-fusible disconnect options. It’s a practical choice when you need dependable isolation, streamlined maintenance, and robust protection in a compact form.
