At 690 V the switching capacity drops to 1 A — the contact gap and arc chamber limit the voltage withstand, not the current-carrying cross-section. Mechanical life is listed at 10 million operations typical, which aligns with the S00 frame's duty cycle for auxiliary switching in PLC output isolation or contactor coil control. ## Ambient limits and clearance for dirty environments The 6 mm side clearance and 10 mm clearance above/below the contactor are the minimum air gaps for PD3 with a 400 V system. This matters when the panel layout forces a non-vertical rail. The substance prohibitance date of 10/01/2009 indicates RoHS compliance was established early; the contactor is also REACH-compliant per Siemens standard declaration.","metaTitle":"Siemens 3RH2244-1AP60 SIRIUS Auxiliary Contactor, 4 NO, S00","metaDescription":"Siemens SIRIUS 3RH2244-1AP60 auxiliary contactor, 4 NO contacts, size S00.
