- Description
The ABB 1SDA104798R1 is an AUX-C 3Q+1SY auxiliary contact accessory cabled for withdrawable Tmax XT5 and XT6 circuit breakers. It delivers four AC changeover (SPDT) contacts at 250 V, pairing three breaker-position signals with one tripped-indication contact for panels that need wider status monitoring. The block ships loose or configurable in single-piece quantities.

Selection Notes
Four CO contacts let the 1SDA104798R1 feed three independent position signals plus a trip indication into a single PLC input card, cutting the terminal count versus wiring two smaller blocks. The 250 V AC rating lines up with the control voltage already used across the XT5/XT6 auxiliary contact family, keeping wiring practice consistent on a switchboard. Select a lower-contact-count block instead when the panel only needs trip status or a single position signal.
