It carries three normally-open instantaneous contacts and no delay or make-before-break logic. That means it closes the instant its coil picks up and opens the instant it drops out, with no intentional overlap. Sized in the S00 frame, it fits the same DIN-rail footprint as the SIRIUS contactor family it complements.
Mounts by screw or snap-on onto a DIN rail. The 45 mm width and 57.5 mm height match the S00 contactor envelope — it stacks directly beside or under a 3RT1 contactor without extra panel space. Depth is 72 mm, which clears most standard enclosure depths. Terminal capacity accepts 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm² solid — covers control wiring from signal-level to moderate power.
That matters when the auxiliary contacts feed a PLC input or a safety relay — low-energy circuits where oxide films on standard contacts can cause intermittent opens. The 10 A rating at 24 V covers the coil load of a medium contactor or a bank of indicators. At higher voltages the current drops: 6 A at 230 V, 3 A at 400 V, 1 A at 690 V.
