The CAE40B6 is a Schneider Electric Easy TeSys control relay with four normally-open (4NO) contacts, a 24V AC coil, and a rated operational voltage up to 690V.
Rated for utilisation categories AC-15 and AC-14, meaning it's designed for switching electromagnetic loads (contactors, solenoids) and resistive loads at control-circuit voltages. The 4NO contact configuration gives you four independent make contacts — common for pilot-duty interlocking or PLC output extension. Meets EN/IEC 60947-1 and EN/IEC 60947-5-1, the core standards for low-voltage switchgear and control-circuit devices. Also compliant with GB/T 14048.1 and GB/T 14048.5 for Chinese-market installations. TH protective treatment per IEC 60068 means it's treated against humidity and tropical conditions — relevant if the panel sees condensation. Ambient temperature range of -20 to 70 °C operating, -60 to 80 °C storage — covers typical industrial enclosures.
