The three switch control shown can operate a three phase set of any single pole solenoid operated switch shown in the VES Co. catalog except the VBU™ switch.  It can be either a zero voltage or a regular control depending on the firmware installed.  The three switches will achieve simultaneous contact closure within 2 milliseconds with minimal adjustment effort.  The use of this control will substantially reduce the effort required to adjust switches for simultaneous operation when operated on 125VDC.  When this control is used for zero voltage closing, sense leads are run out to the deenergized switches to measure their closing times.  A laptop computer with a special program is connected to the control and is used to measure the closing time and to set the calibration.
