•   A powerful and economical solenoid powers RA Transfer Switches.

  •   Independent break-before-make action is common for 2-pole.

  •   Mechanical interlock prevents simultaneous closing of normal and emergency contacts.

  •   Electrical interlocks prevent simultaneous closing signals to normal and emergency contacts and interconnection of normal and emergency sources through the control wiring.

  •   Long-life, high pressure, silver alloy contacts resist burning and pitting. Contacts are mechanically held in both normal and emergency positions for reliable, quiet operation.
