Schneider Electric LGL36400U33X

The circuit breaker in question is a 400A, 3-pole unit designed for operational voltages of up to 600VAC, featuring an interrupting rating of 18kA. It incorporates a MicroLogic 3.3S electronic trip unit that provides advanced protection with an LSI function. This unit is equipped with lugs for both the line and load sides, facilitating straightforward installation.

The PowerPacT L-Frame circuit breakers employ dual-break rotating contacts that minimize peak current during short circuit conditions, enhancing reliability. With a continuous current rating set at 80%, this breaker is suitable for various applications, complying with multiple standards including UL, CSA, NOM, and IEC, and is CE marked.

Designed for operation in ambient temperatures ranging from -2 to 70 °C and capable of withstanding storage temperatures from -50 to 85 °C, this circuit breaker operates effectively at altitudes below 2000 m without derating. The front cover has an IP40 degree of protection to safeguard against dust ingress.

Additional features include a toggle control type and local signaling capabilities with LED indicators for system readiness and alarms. The mounting mode is unit mount with lugs, and it has a net weight of 6.2 kg. The suitability for isolation is confirmed as per IEC 60947-2 standards, making it versatile for diverse electrical distribution needs.
