Description  
of Operation

The single-phase Elastimold

®

 MVR is controlled and 

operated by the SEL

®

 351RS Kestrel control via a 10-pin 

interconnecting cable. The three-phase Elastimold

®

 MVR  

can be controlled either directly with the SEL

®

 651Rx2 

control via a 32-pin interconnecting cable or by a SEL

®

 

351R or 351R Falcon control via a 14-pin cable connected 
to an MVR power module, which then connects to the 
recloser. This manual will cover the set-up and installation  
of your new Elastimold

®

 MVR Recloser. For information  

on SEL

®

 controls and their operation, please refer to  

their respective manuals.
