Disconnect Switches We Offer

Our selection includes trusted brands and enclosure styles to suit virtually any industrial application.

Fusible Safety Switches

Fusible Safety Switches

Fusible disconnects provide short-circuit protection and meet NEC service entrance requirements. Ideal for high SCCR applications, these NF-rated switches accept a variety of fuse classes, including J, R, and H.

Non-Fusible Disconnects

Compact and economical, non-fusible disconnect switches offer a reliable means to manually isolate equipment for maintenance. These are commonly used for motor loads when protection is handled upstream.

Non-Fusible Disconnects
Enclosed Motor Disconnects

Enclosed Motor Disconnects

These all-in-one motor disconnects combine a switch and enclosure, making them ideal for local servicing points on rooftop units, pump panels, or machinery.

Applications for Disconnect Switches

Wistex disconnects are field-proven across a wide range of industrial and commercial systems.

  • HVAC units
  • Machine tools
  • Pump panels
  • Rooftop equipment

Complete your motor control system with contactors and soft starters.

Why Choose Wistex for Safety Disconnects

Wistex is trusted for code-compliant solutions that meet real-world demands. We stock a wide range of fusible and non-fusible disconnect switches, with amperages from 30 A to 2000 A, and enclosure options built for your environment. Our experts can help you build out complete solutions with fuse kits, mounting hardware, and made-in-USA selections, all ready to ship fast.

Disconnect Switch FAQs

Need help choosing or sizing a disconnect switch? Start with these commonly asked questions.

A fusible disconnect switch is typically required when short-circuit protection is needed at the point of service, such as service entrances or fault-current applications. Many local codes also specify fusing for added safety.

To size a switch, multiply your motor's Full Load Amps (FLA) by 115%, consider voltage and phase, and select the correct fuse class. Browse our 30A disconnect switch options or filter by amperage to find your match.

A disconnect switch provides a safe means to isolate power, but unlike a circuit breaker, it does not offer overcurrent protection. Disconnects are ideal for lock-out/tag-out compliance and scheduled maintenance.
