over voltage rdk290

Hello, I have some basic questions in RDK290...   


1 - In an over voltage condition, (disconect load), the current flowing through VR3 and Q2 base will not to burn VR3, Q3 and D7 ??  Or the action of this circuit is sufficient fast ?    Perhaps a series resistor with VR3 limits the current.  In my prototip It was necessary to put a resistor in serie with VR3.


2 - The peak dischargin current of C6 circulating in Q2 base, is sufficent limited by R20 ?  


Thanks for your comments. 

There should be a series resistor on VR3. I'll forward this to the enginneer of the RD290 for correction.
