Electrical Trader stocks a wide selection of surplus and used dead tank breakers (DTBs) ready for immediate shipment. Our inventory includes high-voltage outdoor dead tank circuit breakers from leading manufacturers including ABB, Siemens, Hitachi, and Southern States, spanning voltage ratings from 69kV through 345kV.

 

Dead tank breakers are specified for transmission-level substation applications where the interrupting mechanism sits below ground potential inside a grounded steel tank — making them ideal for high-seismic zones and installations requiring a low center of gravity. Our surplus inventory includes units pulled from utility upgrades and substation refurbishments, inspected and available at a fraction of new replacement cost.

 

Browse our in-stock surplus dead tank breakers by voltage class below, or contact us with your specific requirements — kV rating, interrupting capacity (kA), manufacturer, or vintage — and our team will source what you need. All equipment ships from our US warehouse.
