S00 auxiliary contactor for signal switching and interlocking
The 3RH2431-1AP00 is a SIRIUS auxiliary contactor in size S00, carrying 3 normally-open and 1 normally-closed instantaneous contacts. The DC switching capacity is limited by the arc extinction; at 24 V DC it handles 10 A, but at 220 V DC it's down to 1.2 A. Mechanical life is 5 million operations typical — that's the contactor body, not the contacts.
DIN rail fit and panel clearances
The S00 footprint is 57.5 mm high, 90 mm wide, and 73 mm deep — that's a compact block for a 4-pole auxiliary. Stack them tight and the arc flash clearance gets pinched. That covers standard control wiring up to 12 AWG.
Environmental limits and compliance
Relative humidity minimum is 10% — no upper limit stated, but the pollution degree 3 rating implies it tolerates condensation. The RoHS compliance date is October 1, 2009, so it meets the EU directive for equipment placed on the market after that date. That's a standard operating band for SIRIUS contactors — the coil holds in down to 80% of nominal, which covers brownout conditions in industrial plants.
