Side Mount Rotary Disconnects

This device mounts to the side of your enclosure, and can be ordered with or without a door interlock, left or right side mounting, dependent upon your application. We have taken away all the time and frustration of measuring where and how to mount these, by supplying a template with each unit for drilling locations for both the disconnect and the door interlock. Model dependent, 65kA or 100kA SCCR for class CC fused disconnects, and up to 200kA SCCR rating for class J fused disconnects, and are UL, CSA, IEC and CE marked.

Ford Power Supply Disconnects (PSD)
We worked hand in hand with Ford Motor to design a transformer disconnect that not only supplies AC power, but 24VDC power as well. The AC transformer can be 1K, 2K or 3KVA, and the 24VDC can be 10 or 20 amp. The AC transformer is mounted in itโs own vented enclosure mounted on the top of your control cabinet to keep the heat out, while the disconnect, fuses, DC power supply are mounted in either a Nema 1 enclosure to mount inside your cabinet, or a Nema 12 style to mount outside your control cabinet. Designs include North America, as well as global voltages. Many models are approved and marked cULus.
