Notes
L = Width of circuit-breaker.
I = Horizontal poles center lines.
A = Upper and lower distance.
ø = Diameter of the isolating contact.
8.3. Control circuit power supply
The energy for circuit-breaker operation is supplied by one or more capacitors which are kept
charged by a feeder which also sees to supplying the electronic circuit with power.
This guarantees correct operation even if the auxiliary power supply does not reach the rated
value.
Thanks to the use of low consumption components, the feeder consumption is about 15 watt with
the circuit-breaker either closed or open.
After each operation, the feeder consumes about 110 watt for a few seconds to restore the opti-
mal charging level of the capacitors.
The charging condition of the capacitors is monitored constantly by the electronic module which
also sees to the opening, closing, signalling, etc. functions.
Two feeders are available:
type 1: 24...48 V a.c. / 24...60 V d.c.
type 2: 100...240 V a.c. / 110...250 V d.c.
