Meet the Square D MHL363501212 circuit breaker—a rugged, industrial-grade protection device engineered for demanding three‑phase power systems. With a 350‑amp capacity and a 3‑pole configuration, this breaker is designed to interrupt fault currents on up to 600V networks, helping to protect both equipment and personnel during faults or overloads. Ideal for maintenance, retrofit, and replacement projects, it provides a reliable path back to steady operation when original components reach the end of life.
Why this Square D breaker stands out: it’s built to align with the original equipment specifications for 3‑phase distribution, delivering consistent protection without invasive panel modifications. By matching the precise amperage, pole count, and voltage, it minimizes downtime and wiring changes during service or upgrades, helping you restore operation quickly and safely.
