The Schneider Electric TeSys LG LG1K065M705A37 is an enclosed direct-on-line (DOL) starter that integrates a contactor, switch disconnector, and circuit-breaker in a single IP55 polycarbonate enclosure. It is rated for AC-3 utilisation category, meaning it is designed for starting and stopping squirrel-cage induction motors under load. The thermal protection adjustment range of 0.63...1 A sets the overload relay trip point, so the starter protects the motor against sustained overcurrent. At 400/415 V AC 50/60 Hz, it handles motor loads up to 0.25 kW. The front panel includes a white push-button for start, a black push-button for stop, a red rotary-handle emergency stop, and a red mushroom-head push-button emergency stop — both emergency-stop functions provide a local, hard-wired off command that satisfies IEC 60204-1 and IEC 60947-4-1 requirements for safety circuits.
The enclosure measures 165 mm deep by 175 mm wide by 165 mm high, built from polycarbonate with an IK07 impact rating. Four cable entries — two Pg 13 and two Pg 16 at both top and bottom — give flexibility for incoming supply and outgoing motor cables without needing an external junction box. The IP55 rating means the enclosure withstands water jets and dust ingress, making it suitable for installation in washdown areas or outdoor locations where the starter must be protected from the elements. This is a standard-environment device, not rated for corrosive atmospheres or extreme temperatures. For food-and-bev or chemical processing lines where aggressive washdown chemicals are used, verify compatibility of the polycarbonate housing and the IP55 seal with the specific cleaning agents on site.
