Product details

Panel fit and mounting flexibility

The 3RH2431-1AB00: Its dimensions — 57.5 mm high, 90 mm wide, 73 mm deep — fit the compact S00 footprint common in Siemens modular control assemblies.

Contact ratings across the voltage range

These values reflect the contactor's thermal and switching capability per the S00 frame. These parameters matter when coordinating with upstream protective devices in a control circuit.

Environmental and compliance profile

Relative humidity minimum is 10 %. The product carries a substance prohibitance date of 10/01/2009, indicating RoHS compliance from that date forward.
