Schneider Electric LE36100LSG Circuit Breaker

Schneider Electric's Square D LE36100LSG is a 3-pole molded‑case circuit breaker designed for 600 V systems and 100 A continuous protection. Built on the LE (L-frame) platform, it features a Micrologic electronic trip unit (Series B) with LSIG functionality, delivering Long‑Time, Short‑Time, Instantaneous, and Ground-Fault protection and rated for 100% operation. The unit is designed for I‑Line plug‑in mounting in compatible Square D panels, offering a compact, field‑installable solution for feeder or branch‑circuit protection in industrial and commercial power distributions. Key specifications include a 3‑pole configuration, 600 VAC rating, and a 100 A ampere rating, suitable for protecting motor feeds, distribution panels, and other heavy‑duty circuits where precise coordination with upstream devices is essential. The LSIG designation denotes the 100% rated trip capability with the integrated rating plug, enabling accurate coordination within multi‑breaker assemblies. For replacements or retrofits in legacy Square D installations, the LE36100LSG provides a common form factor and trip architecture, simplifying upgrades without sacrificing protection performance in demanding environments such as manufacturing floors, data centers, and large facilities. In short, this MCCB combines robust electronic protection with a 3P, 100 A, 600 V spec in a plug‑in LE frame, making it a precise, compatible choice for reliable circuit protection across medium‑voltage distribution panels.
