Each contact is rated 10 A at 24 V and also 10 A at 230 V, so it handles both 24 VDC control loops and 230 VAC pilot circuits at full rated current. The instantaneous contacts close and open within 4 to 15 ms (AC) and arcing time runs 10 to 15 ms, which is standard for electromechanical auxiliaries in this frame. If you're paralleling contacts for higher current, watch the total package limit — the 10 A per contact is the individual rating, not a summed bus. ## Mounting and clearances — what fits around it The 3RH2140-4AG60 measures 73 mm deep by 45 mm wide by 57.5 mm high. That 6 mm side gap is tight — you can stack these on the rail with almost no air between them, but if you're mixing with heat-generating devices (contactors under continuous load, power supplies), leave the full 10 mm vertical breathing room. ## Environmental tolerance for a mill floor That covers a hot motor control center in summer and a cold warehouse in winter without derating. Relative humidity down to 10 % — no problem for dry climates or air-conditioned rooms. The RoHS compliance date of October 1, 2009 means the part has been lead-free since that revision; it's also REACH-compliant by Siemens standard declaration.","metaTitle":"Siemens 3RH2140-4AG60 SIRIUS Auxiliary Contactor, Size S00,","metaDescription":"Siemens SIRIUS auxiliary contactor 3RH2140-4AG60.

The difference is contact configuration: 3RH2140-4AG60 carries four NO contacts, while 3RH2131-2AK60 has a different contact arrangement.
