Air Circuit Breakers

An Air Circuit Breaker (ACB) is a robust circuit protection device that uses air as the arc-quenching medium to interrupt fault currents. Designed for high ampere ratings (typically 630A to 6,300A), ACBs excel in protecting main power distribution systems from overloads, short circuits, and ground faults. Their advanced trip units and modular design make them ideal for critical applications demanding precise control and minimal downtime.

Key Features of Schneider ACBs (Masterpact Series):

• Ultra-High Breaking Capacity: Up to 200kA (IEC 60947-2), ensuring protection in extreme fault conditions.
• Adjustable Protection Settings: Customize overload (Ir), short-circuit (Isd/Ii), and ground fault (Ig) thresholds via intuitive interfaces.
• Smart Connectivity: Integrated communication modules (Modbus, Ethernet, IEC 61850) for real-time monitoring via EcoStruxure Power Advisor.
• Modular Design: Easily upgradeable with accessories like shunt trips, auxiliary contacts, and energy meters.
• Durability: Designed to withstand harsh environments, with high mechanical and electrical endurance.

Key Benefits of Choosing Schneider ACBs

• Maximized Uptime: Rapid fault interruption minimizes downtime and equipment damage.
• Customizable Protection: Tailor settings to match system requirements, reducing nuisance tripping.
