Siemens Energy has launched a new distribution recloser. Designated the SDR, this new recloser is manufactured in multiple Siemens locations, including Germany, the United Kingdom and Wendell, North Carolina. The recloser switch unit uses vacuum technology for circuit interruption; it is insulated in a cycloaliphatic epoxy molding and uses a dual coil, low-energy, magnetic actuator.

“The key to the exceptional performance of the SDR is its 7SR controller,” said Brad Luyster, business segment manager for outdoor medium voltage utility products. “Developed by Siemens, this state-of- the-art controller has several unique features that will please linemen and engineers alike. It features an intuitive, human-machine interface for programming the controller, a USB communication port for connection to a laptop and a fully withdrawable controller, which can be pulled from the front of the control cabinet and replaced in minutes – real plug and play,” added Luyster.

It features ratings of up to 38 kV, 800 Amps continuous and 16 kA interrupting. Options for triple-single and loop automation are available, as well as fault detection.
