250V AC/DC and 24V AC/DC auxiliary contacts are installed without the need for any screws. They are extremely easy to fit. Simply apply a slight pressure in the appropriate place. The following versions of auxiliary contacts are available: • cabled (AWG20 cable section -0.5mm 2 ): - for fixed/plug-in circuit-breakers with 3.28ft long cables; - for withdrawable circuit-breakers with fixed part and moving part connector; • not cabled: - for fixed/plug-in circuit-breakers with cables from AWG 20 up to AWG 15 cross-section. Auxiliary contacts are supplied for each circuit-breaker in the SACE XT family in various different com- binations, as shown in the table. The following items can be ordered to make the installation even more flexible: • an uncabled auxiliary contact can generate different signals (Q, SY or S52) according to the position where the circuit-breaker is installed; • an uncabled S51 auxiliary contact, which can be used for XT2, XT4, XT5 and XT6 circuit-breakers; • a cabled auxiliary contact, with unnumbered cables. It can generate different signals (Q, SY or S52) according to the position where the circuit-breaker is installed.
