SIRIUS S00 auxiliary contactor — 4 NO, active production
The 3RH2122-2AP00-ZX95: The 4 NO configuration gives you four isolated signal paths in one 45 mm-wide package.
DIN rail fit and mounting flexibility
This matters when packing multiple contactors in a row — you can butt them side-to-side at 6 mm spacing.
Contact ratings across the voltage range
Mechanical endurance is 30,000,000 operating cycles typical — this is a relay-grade contactor, not a power contactor.
Environmental limits and compliance
Substance prohibitance date is 10/01/2009 — this part complies with RoHS and REACH substance restrictions effective from that date. The ZX95 suffix indicates a special version with specific compliance documentation; confirm the exact declaration package with the order.
