Product details

SIRIUS 3RH2122-1AB00-ZX95 — Auxiliary Contactor, Size S00, 2 NO

Rated operational current at 24 V AC/DC is 10 A; at 230 V AC it also carries 10 A, dropping to 3 A at 400 V AC and 1 A at 690 V AC. The DC switching curve at 24 V is 10 A, 4.7 A at 60 V, and 0.26 A at 600 V — so for DC control circuits, watch the voltage-dependent derating. Arcing time runs 10 to 15 ms at AC.

Integration — DIN Rail and Panel Fit

Dimensions: 45 mm wide, 57.5 mm high, 73 mm deep — the S00 footprint is compact enough for dense panel layouts. Wire termination accepts 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm² solid or stranded conductors.

Frequently asked questions
