Rated for AC-3 utilisation category, it switches motor loads at 4 kW on 220/230 V AC, 7.5 kW on 400/415 V AC, and 9 kW on 440 V AC (all 50/60 Hz). The thermal protection adjustment range of 13-18 A lets you dial in the overload trip point to match the motor full-load current. ## Lifecycle reality — obsolete, but sourced The IP55 polycarbonate enclosure (165 mm high, 175 mm wide, 146 mm deep) with four cable entries (two Pg 13 and two Pg 16 on both top and bottom) is sized for panel or wall mounting in a washdown area — the IP55 rating means it resists dust ingress and low-pressure water jets, so it suits food-processing or outdoor installations where a standard open starter would need a separate enclosure. Compliance with IEC 60947-4-1 (the standard for contactors and motor-starters) and IEC 60204-1 (safety of machinery — electrical equipment) means this starter is certified for the safety circuit of a machine where the emergency-stop mushroom head is wired into the control loop.","metaTitle":"TeSys LG7D18B720 Enclosed DOL Starter, 13-18A, 24V AC","metaDescription":"TeSys LG7D18B720 enclosed DOL starter, 13-18A thermal range, 24V AC coil, IP55.
