Industrial NE361200LSG Three Phase Circuit Breaker

Square D NE361200LSG is a 3‑pole, 1200 A, 600 V I‑Line molded‑case circuit breaker from Square D (Schneider Electric) equipped with a LSIG Micrologic electronic trip unit for long‑time, short‑time, instantaneous, and ground‑fault protection. This NE‑frame device ships with a 40% rating plug installed, enabling a reduced continuous‑amp setting to tailor protection for specific feeders. The four terminal positions accept conductors up to 3/0 AWG, or up to 600 kcmil, in both aluminum and copper, making it suitable for high‑current feeder applications. Designed for industrial power distribution, the NE361200LSG integrates in Square D NE‑frame switchgear with plug‑in I‑Line mounting for easy installation in compatible panels and enclosures. With a 1200 A frame rating and 600 V maximum voltage, it protects large feeders and motor circuits while providing adjustable trip characteristics through the Micrologic LSIG module. This model is commonly used in manufacturing, processing plants, and other facilities requiring reliable, high‑ampere protection and coordination with upstream devices, transformers, and distribution gear. The LSIG trip functions deliver configurable timing and fault protection, supporting applications that demand precise protection without sacrificing service continuity.
