Air Circuit Breaker Arc Chute with DC01 Steel De-ion Plates for ACB Arc Chamber（3011134）

Heavy-Duty Safety Core of ACB Air Circuit Breakers

In low- and medium-voltage power distribution networks, Air Circuit Breakers (ACBs) serve as the primary protective barrier for main incomers and high-capacity feeder lines. During severe fault current interruptions, the Arc Extinguishing Chamber is the decisive component defining the safety limits and breaking performance of the switchgear.

Engineered with a heavy-duty 28-de-ion plate configuration and PA46-GF30 gas-evolving inserts, the 3011134 ACB Arc Chamber delivers swift arc elongation, rapid voltage buildup, and efficient plasma cooling, ensuring total fault interruption within milliseconds.

Key Technical Parameters & Material Specifications

Engineered Arc Extinguishing Mechanism

• Rapid Multi-Arc Splitting: The 28-plate DC01 stack instantly draws the electric arc away from contacts, subdividing the high-energy arc into 29 short micro-arcs in series.

• Cumulative Voltage Drop: Leveraging anode-cathode near-electrode voltage superposition across all 28 grids, quickly driving arc voltage above system recovery voltage to force current extinction.

• Gas-Dynamic Ablation: Under intense arc heat, PA46-GF30 quenchers blast cool deionizing gas into the plasma channel, rapidly lowering conductivity and eliminating restrikes.

• Mechanical Shock Resistance: High-grade melamine glass cloth board maintains strict plate gap tolerances during severe electromagnetic blowout stresses.

Industrial Applications & Core Value

Widely deployed across heavy industrial power systems, data center incoming panels, high-rise utility distribution, and renewable energy collector substations. Designed to optimize breaker ultimate breaking capacity (Icu) and service breaking capacity (Ics), extend main contact service lifespan, and ensure round-the-clock power reliability.
