Auxiliary position contacts - AUP
These allow information about the position of the circuit-breaker in relation to the fixed part of plug-in
or withdrawable versions to be routed outside the circuit-breaker itself.
Two types of position contact (AUP) are available, at 250V AC/DC and 24V AC/DC:
Q
racked-in contact for all plug-in and withdrawable SACE Tmax XT circuit-breakers, to be posi-
tioned in the fixed part;
Q
racked-out contact for all withdrawable SACE Tmax XT2 and XT4 circuit-breakers, to be installed
in the side part of the withdrawable version.
For further details about the electrical specifications of the contacts, consult the “24V DC and 250V
AC contacts” section of the Accessories chapter.
