Appleton DS16U - 39A, Disconnect Switch

Engineered for reliability in challenging environments, the Appleton DS16U - 39A Disconnect Switch delivers robust on/off isolation plus dependable overcurrent protection in a compact form factor. This fusible switch is designed to simplify motor control and power distribution where space is at a premium and serviceability matters.

What makes the DS16U stand out

• 39A current rating makes it well-suited for motor disconnects, helping protect small to mid-size motors and branch circuits without oversized hardware.
• Compact, maintainable design fits into tight panel spaces and offers accessible maintenance, making fuse changes and servicing straightforward.
• Integrated isolation and protection combines safe de-energization with overcurrent protection in a single unit, reducing wiring complexity and potential fault points.
• Versatile installations ideal for panelboards and branch circuit protection across industrial and commercial settings.

Ideal applications

Use the DS16U to power down motors in conveyors, pumps, fans, and processing equipment, or as a primary disconnect in control panels and branch circuits. Its compact profile lets you retrofit or add protection in spaces where larger switchgear won’t fit, while maintaining clear, local isolation for safety and compliance during maintenance.

Practical considerations and tips

For a streamlined electrical layout, pair the DS16U with the circuits it serves and coordinate with your control wiring to ensure clear, intentional switching. Because it’s a fusible switch, plan for regular fuse inspections and timely replacement to maintain continuous protection and minimize downtime.
