RAM - Load Break Switchgear
RAM - Load Break Switchgear
G&W Electric RAM padmount and vault switchgear feature load break switching capability in a totally sealed, dead front device. The switches are designed for use on 3-phase systems with voltages up to 38kV, 900A load break and continuous current, and 40kA asymmetrical momentary and close into fault ratings. They feature available compact footprints with front or top access construction. These switches are extremely flexible and are offered in many different styles. The high voltage connections can be positioned on the bottom, top, or side to ease cable training and installation.
The switches are designed to IEEE C37.72 and C37.74 for load break capability. Padmount enclosures are designed and tested to IEEE C57.12.28 and C57.12.29.
Features and Benefits
Construction - Available compact construction with front accessible switch operators and bushings. Vault construction is also available with top or bottom bushings or top access to operators and bushings.
Visible Break - All ways are equipped with visible break to view the open and closed positions.
Voltage Sensing - Available integral voltage sensing for use with voltage indication panel to determine in-phase condition or for use with a relay with up to 1% accuracy.
Seismically Certified - The switches are available for order designed per the guidelines of ASCE (American Society of Civil Engineers) standard 7-05 Chapter 13. These guidelines cover the design of non structural components installed in a building. The switches also underwent a test regime specified by ICC-ES-AC-156 (International Code Council Evaluation Services Acceptance Criteria) which specifies the shaker table test inputs applied to the switches. Certified for use in OSHPD (Office of Statewide Health Planning and Development) projects for healthcare facilities in the State of California. The OSHPD application number on file is OSP-0157-10.
Automation - Available for motor automation with portable or permanently mounted motor and controls. A variety of relays such as SEL, ABB, and GE are available with G&W Electric programming and cabinet construction. Cabinets can be ordered in a low voltage enclosure for padmount, pedestal or IP68 rated submersible for vault installed switchgear. Programming for automatic source transfer, or LaZer custom solutions are available.
