Square D ME36250LI I-Line Molded Case Circuit Breaker

The Square D ME36250LI I-Line molded‑case circuit breaker is a 3‑pole, 250‑amp device rated for 600 V, designed for use in Square D I‑Line panel systems to protect feeders and equipment in industrial and commercial power distribution, including service entrances, motor control centers, and large branch circuits, with plug‑in mounting that simplifies installation and replacement in compatible panels. Powered by the LI trip unit, it provides long‑time and instantaneous protection with a solid‑state trip mechanism to quickly interrupt faults while minimizing nuisance trips, and it supports coordinated protection with other LI‑series devices through standard trip curves and settings. Designed for plug‑in installation in compatible Square D panels, this breaker protects 3‑phase circuits in 600 V systems and serves as a main feeder or branch‑circuit protective device in industrial environments, offering robust protection for motors, transformers, and sensitive loads in harsh manufacturing or processing settings. Manufactured by Square D (Schneider Electric), it is part of the LI line of molded‑case breakers and is compatible with LI trip modules and accessories for coordinated protection in electrical distributions, with a long‑standing history in industrial power systems.
