The Schneider Electric LC1E1810B7 is a 3-pole contactor from the Easy TeSys Control series, rated for 18 A in AC-3 duty at ≤440 V. The 24 V AC coil (50/60 Hz) pulls in reliably across the -5 to 55 °C operating range, and the 1NO auxiliary contact gives you a feedback or seal-in circuit without adding a side-mount block.
Integration notes
DIN-rail mount, 45 mm wide, 74 mm tall, 80 mm deep. The 24 V AC coil draws about 0.2 A at 50 Hz (typical for this frame size). The 1NO auxiliary is wired to terminals A1/A2 for the coil and 13/14 for the NO contact. If you need more aux contacts, the Easy TeSys range uses a clip-on side-mount block — no tools needed. The non-overlap timing (1.5 ms each way) is built in, so you don't need external timing relays for mirror-contact safety circuits.
