The Schneider Electric CAE40Q5 is an EasyPact TVS control relay from the Easy TeSys range, designed for switching control circuits. It carries 4 normally-open (NO) poles rated for operational voltages up to 690 V, with a control voltage of 380 VAC. The relay is rated for utilisation categories AC-15 and AC-14 per EN/IEC 60947-5-1, meaning it is suited for switching electromagnetic loads (contactors, relays) and resistive/inductive control loads at currents below the contact rating. The 4 NO configuration gives you four independent make contacts in a single 45 mm wide package — useful for compact panel layouts where you need multiple control signals from one coil.
The relay complies with EN/IEC 60947-1 (general rules for low-voltage switchgear) and EN/IEC 60947-5-1 (control circuit devices), as well as the Chinese GB/T equivalents. It carries IP2X finger protection per IEC 60529, so it is safe for open-panel mounting where accidental contact is a concern.
