Affordable Eaton / Cutler-Hammer LA3400PR – 400A 3 Pole Molded Case Circuit Breaker

Built for heavy-duty commercial applications, this 400A, 3-pole current-limiting MCCB utilizes a Tri-Pac fused design. It provides reliable thermal-magnetic protection with an adjustable magnetic trip. Designed for bolt-on installation, this breaker fits into legacy Westinghouse and Eaton switchboards and motor control centers. When upgrading, the LCL3400 serves as the modern replacement. With a 200 kAIC rating at 600VAC, it effectively restricts let-through current during severe faults.
