Schneider Electric LA36400 I-Line Circuit Breaker

Schneider Electric's LA36400 is a 400 A, three-pole I-Line molded-case circuit breaker (MCCB) engineered for plug-in I-Line panelboards. This Type LA, thermal-magnetic device provides a 600 V AC maximum rating and a 250 V DC rating, with an AC interrupting capacity of 22 kA at 600 VAC and a DC interrupt rating of 10 kA at 250 VDC, enabling reliable protection for mixed‑voltage distributions. The unit is a 3-pole breaker designed for quick installation in compatible panelboards and carries the I-Line form factor for straightforward upstream and downstream protection of feeders and motor circuits. In industrial and commercial power distribution, it protects 400 A circuits in feeders and MCCs, delivering precise trip characteristics and proven reliability for demanding environments. Compatible with Square D I-Line plug-in bus systems for quick swap-out and streamlined maintenance in industrial installations.
