The Diamondback switch is a solid dielectric, three-phase load break switch for overhead applications. The Diamondback switch combines the time-proven reliability of vacuum bottles with the maintenance-free benefits of a solid dielectric insulated device. Diamondback is designed for three phase automatic or manual switching operations providing circuit isolation for systems rated up to 29.3 kV, 630A continuous current. The compact, light-weight design provides ease of installation. The Diamondback has been designed and tested to comply with the IEEE C37.74 and IEC 62271- 103 (formerly IEC 60265-1:1998) standards.
Accessories
Controls Connections: The 37-pin connector and control cable make the connection between the Diamondback switch and the control, providing operation, status, and current and voltage monitoring capabilities. Two cables are provided: (1) power cable, and (1) control cable.
