Square D by Schneider Electric LAL36400 Circuit Breaker Enclosure

Square D by Schneider Electric LA-400-S is a NEMA 1 indoor circuit breaker enclosure designed for surface mounting and intended to house LAL and LHL molded‑case breakers, providing a secure, code‑compliant housing for distribution components. It is rated for 125–400 A and up to 600 V, supports 2‑ or 3‑pole configurations, and is built to accept LA‑series breakers in compatible assemblies for streamlined installation in commercial or light‑industrial environments. This enclosure is commonly paired with the LAL36400, a 400 A, 3‑pole molded‑case breaker that features standard line and load terminals on the breaker and is designed for use within LA/LAL/LHL family installations, enabling straightforward wiring and reliable protection. Leveraging the I‑Line LAL/LHL frame compatibility, the LA‑400‑S provides a robust, maintenance‑friendly housing that protects a complete indoor distribution arrangement while offering accessible wiring interfaces for service, maintenance, and code‑compliant operation.
