Schneider Electric LAL36300MB Circuit Breaker

Schneider Electric's Square D LAL36300MB is a 300 A, three-pole molded-case circuit breaker (MCCB) in the LA family, rated for 600 VAC with a 22 kAIC interrupting capacity and a 250 VDC rating. The MB suffix denotes a lug-equipped configuration for cable-in/cable-out connections and a short-handle operator for manual isolation. This thermal-magnetic breaker provides fixed-trip protection for three-phase feeders and motors, making it suitable for industrial and commercial power-distribution panels where robust protection and fast disconnection are required. The LAL36300MB protects three-phase circuits up to 600 VAC, supporting typical industrial loads such as feeders, switchgear, and motor control applications that demand reliable overload and short-circuit protection in demanding environments.
