- Description
CAE31B5 is Schneider Electric's Easy TeSys control relay in a 3NO+1NC arrangement, carrying a 24 V AC coil and a 140 A rated making capacity at up to 690 V. Rated for AC-14/AC-15 duty at up to 180 cycles/min, it duplicates pilot signals in control circuits and terminates on screw clamp terminals on DIN rail or a mounting plate.

Selection Notes
The 3NO+1NC contact set gives three make contacts covering parallel command signals alongside one break contact for interlocking. This Easy TeSys range is certified CE, CCC, EAC and BIS but carries no UL or CSA listing, so it fits IEC-standard markets; panels that need UL 508 traceability for North America should use the TeSys K (CA2K) or TeSys Deca control relay instead. At 180 cycles/min maximum operating rate it suits standard-duty pilot switching rather than high-cycle automatic sequencing.
