Auxiliary Position Contacts – AUP
Auxiliary position contacts provide information about the position of the circuit-breaker in relation to
the fixed part of plug-in or withdrawable versions.
Three types of position contacts (AUPs) are available:

• racked-out contact for all withdrawable Tmax XT circuit-breakers;
• test contact for withdrawable Tmax XT5, XT6, XT7 and XT7 M circuit-breakers.
