The 3RH2122-1AB00-ZW96: It switches auxiliary circuits in motor starter and control transformer applications where the main contactor's auxiliary contacts are already consumed or where a separate signalling block is needed.
Mechanical endurance is 30 million switching cycles typical, with arcing time between 10 and 15 ms and a DC switching rate of 10,000 operations per hour.
Environmental ratings and compliance — -25 to +60 °C operation, RoHS dated 2009
Substance prohibition date of 10/01/2009 aligns with RoHS compliance. Relative humidity minimum is 10% — the contactor is not rated for condensing atmospheres without additional enclosure protection.
