Panel fit and contact rating for a 4 NO auxiliary block
The 3RH2244-1AP60: Depth is 117 mm, height 57.5 mm. 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.
