Trip auxiliary contact - SY
The XT7 circuit-breakers can be equipped with auxiliary contacts that signal that the circuit-breaker is
opening due to the intervention of the trip unit, or to the opening of undervoltage/shunt opening re-
leases, or to the use of the test button. The contacts are available in the following configurations:
400V/250V AC/DC contact 24V DC contact
Type Switching Switching
Minimum load 100mA @ 24V 1mA @ 5V
Breaking capacity
DC 24V - 0.1A
125V 0.3A -
250V 0.15A -
AC 250V 12A -
400V 3A -

Contact signaling the tripping of the protection unit Ekip – S51
This contact signals the opening of the circuit-breaker after the Ekip protection trip unit has tripped.
The contact is available for the XT7 and XT7 M.
For the XT7 M circuit-breaker, the closing operation can be carried out only after the “TU Reset” push-
button has been restored to its normal operating position. The switching contact can also be associ-
ated with an optional accessory for remote resetting - YR.

Contact signaling tripping of the YO2/YU – S52
This contact signals that the undervoltage (YU) or the shunt opening release (YO2) have been acti-
vated. The contact is the same and depends on the service release mounted in the dedicated position.
It is available for the XT7 only, with YU/YO2 installed in the dedicated slot.
Auxiliary contact S52 doesn't read the tripping of the YO.
