Attached pages gives the power consumption of different auxiliary devices used with SF circuit breakers.
Information summarized below in reference to attached simplified wiring diagram for 110V dc power supply:

Type of auxiliary device	Power consumption (W) @ 110Vdc	Mode of supply/average duration	Re-occurrence
Shunt closing release	50W	short time/50ms	each closing cycle (according to application)
Shunt opening release	50W	short time/70ms	each opening cycle (according to application)
Under voltage release	triggering: 100W latched: 10W	Continuous (10W)	Continuous
Electrical motor with gearing	380W	short time/15s	each closing cycle (re-arming of the closing spring), according to switching cycles/application
