Verify coil voltage and contact count before substituting."},{"question":"Will 3RH1131-2BE40 drop into a panel specified for 3RH2122-1BW40?","answer":"Both are S00 size with the same 45 mm width and snap-on DIN mounting, so mechanical fit is identical. The deciding factor is the coil voltage: 3RH1131-2BE40 uses 60 V DC, while 3RH2122-1BW40 uses a different coil.
