Schneider Electric LHP36400MB Circuit Breaker

Schneider Electric's Square D LHP36400MB is a unit-mount, three-pole molded‑case circuit breaker rated at 400 A for power distribution panels and feeders. Designed for systems up to 600 V AC (and 250 V DC), it provides overload and short-circuit protection with a 25 kA short‑circuit rating at 600 VAC and 50 kA at 250 V DC. The LHP36400MB is part of the LH/LHP family and uses a thermal‑magnetic trip mechanism, with Push‑To‑Trip capability to manually trip the breaker without exposing live parts. This variant supports integration into compatible Schneider Electric panels and MCCB enclosures, making it suitable for main feeders, panelboards, motor‑control circuits, and service entrances in industrial facilities and data centers where robust 400 A protection is required.
