DC Power for Relays: BAT7001
The BAT7001 is a direct current power supply which may be used to provide auxiliary power for relays and circuit breakers.  It takes current inputs from one, two or three line CTs and therefore does not require any other external power source.  

Capacitors are used to store charge for tripping circuit breakers, even after the main power supply has been lost.  The BAT7001 also features two volt-free alarm contacts to alert the control system if the main supply has been lost.
