with integral Fused Service Entrance Disconnect
240V Single Phase 2 pole
Aluminum NEMA 3R Outdoor Enclosure

Reliability. Simplicity. Economy. Safety.
Now you get it all in one box... at a lower cost


The new Ronk Fused Disconnect Double-Throw Switch lets you save money – a lot of it – without giving up any of the features you need. This switch is specially designed to meet your exact requirements. No longer are you forced to buy a three-phase switch when you have only single-phase power. (Some other brands force you to do this).

This industry-first product puts everything you need in one box: “Made in the USA” Ronk reliability, simplicity, economy, and safety, all packaged in an all-aluminum, rain-proof NEMA 3R enclosure.

Best of all, its unique design load-break contact mechanism will not fail due to fouling, is non-jamming, includes a neutral bar and uses best-in-class type “T” fusing.  (Other brands do not include the fuses and usually charge extra for the neutral kit.)  Let us demonstrate how you can increase efficiency, stabilize power usage, and walk away at night knowing that all systems can operate reliably.

For use with standby generators to transfer loads between utility power and auxiliary power.  Two position, with quick-make, quick-break contacts designed to minimize contact arcing and prolong contact life.  Aluminum NEMA 3R outdoor enclosure for wall mounting.  Ample wiring space.  Rated at 240 volts.  Lugs for aluminum and copper wire included.  UL listed.  Manually-operated switch suitable for use in accordance with article 702 of the National Electric Code, ANSI/NFPA 70.  This switch is suitable for use on a circuit capable of delivering not more than 50,000 amperes RMS symmetrical at 240 volts.   Made in USA  

This switch is "Suitable for Use as Service Entrance Equipment."
