We work with customers throughout San Diego and surrounding areas, as well as buyers nationwide looking for standard and hard-to-find electrical supplies.
Electrical disconnects are switches used to isolate a circuit or piece of equipment from its power source. They are commonly installed to provide a means of disconnecting electrical power during maintenance, servicing or emergency situations. Disconnects are also referred to as isolator switches or safety switches. Common configurations include fusible disconnects, which contain fuses for overcurrent protection, and non-fusible disconnects, which provide a means of electrical isolation without incorporating fuse protection. Other designs include knife-blade switches, load-break switches and rotary disconnects. Each type is designed for particular electrical ratings and applications. ESU can help you locate the appropriate disconnect based on your equipment requirements.
When selecting an electrical disconnect, it is important to match the switch to the equipment and electrical system it will serve. Amperage and voltage ratings, number of poles, fused or non-fused configuration, enclosure type and load requirements all affect which disconnect is appropriate. For commercial and industrial installations, the disconnect must also be suitable for the specific application and installed in accordance with applicable electrical codes and manufacturer specifications. If you are replacing an existing unit, having the manufacturer and catalog number available can help identify a compatible replacement.
ESU buys and sells new, used, surplus and obsolete electrical disconnect switches for contractors, maintenance departments and businesses throughout San Diego and nationwide. We can help source disconnects for HVAC equipment, motors, machinery, commercial buildings and industrial electrical systems. We also purchase surplus disconnects and other electrical equipment from businesses and contractors looking to sell unused or excess inventory. Whether you need a replacement for an older installation or have equipment available for resale, ESU can help you explore your options.
