LX36400G - 400 Amp Circuit Breaker

LX36400G - 400 Amp Circuit Breaker

Meet the LX36400G 3-Pole 400A Circuit Breaker—a high-capacity protection device built to deliver dependable performance in heavy-duty systems. Offering electronic trip precision via Micrologic technology and current-limiting capability, this breaker is engineered to detect and interrupt faults cleanly, reducing damage to downstream equipment. Its plug-in architecture makes servicing faster and reduces operational downtime—ideal in demanding industrial and commercial power systems.

Key Features and Benefits

• Micrologic Electronic Trip Control: Offers adjustable long-time, short-time, instantaneous, and ground-fault settings so you can finely tune protection for your system.
• Current-Limiting Behavior: Keeps energy let-through low during fault events, protecting downstream assets from excessive stress.
• Thermal-Magnetic Protection: Blends thermal (overload) and magnetic (short-circuit) sensing for comprehensive overcurrent coverage.
• Plug-In Design: Enables quick insertion and removal without rewiring, making installation and maintenance less labor-intensive.
• Molded Case Construction: Provides excellent mechanical strength and electrical insulation to suit industrial environments.
