To ensure the protection of a user supplied with a network having the following
characteristics:
Rated voltage Ur = 1000 Vdc
Short-circuit current Ik = 18 kA
Load current Ib = 520 A
Network with both polarities insulated from earth.
From the table of available settings, the circuit-breaker to be used is:
T5V 630 In=630 four-pole Icu@1000 Vdc = 40 kA
Thermal trip threshold adjustable from (0.7-1) x In therefore from 441 A to 630
A to be set at 0.85.
Magnetic trip threshold adjustable from (5-10) x In which with correction factor
km = 0.9 gives the following adjustment range: 2835 A to 5670 A. The magnetic
threshold will be adjusted according to any conductors to be protected.
The connection of the poles must be as described in diagrams A or B.
A device which signals any first earth fault must be present.
With the same system data, if the network is carried out with a polarity connected
to earth, the circuit-breaker must be connected as described in diagram C.
