3011081
In residential, commercial, and modular DIN-rail terminal power distribution systems, Miniature Circuit Breakers (MCBs) require rapid short-circuit interruption within extremely constrained modular dimensions. The 3011081 MCB Arc Chamber is engineered to deliver rapid magnetic commutation and immediate arc extinguishing to suppress peak fault energy.
Configured with a 12-plate de-ion grid stack stamped from high-permeability Q195 cold-rolled steel (protected by 2μm anti-ablation nickel plating) and embedded into an integrated PA66-GF30 reinforced bracket, this unit ensures high breaking performance (6kA/10kA) and durable phase insulation.
| Product Part Number | 3011081 (MCB De-ion Arc Chute) |
| Structural Configuration | 12 De-ion Splitter Plates + 1 Integrated Support Bracket |
| Grid Plate Material | Q195 Cold-Rolled Strip Steel (High magnetic suction & high formability) |
| Surface Electroplating | 2μm Precision Nickel Coating (Anti-oxidation, corrosion & arc wear resistant) |
| Integrated Bracket Material | PA66-GF30 (30% Glass-Fiber Reinforced Polyamide, flame retardant & gas-evolving) |
Gas-Dynamic Ablative Quenching: The PA66-GF30 bracket releases micro-quantities of deionizing cooling gas under intense arc heat, optimizing internal flow fields and quenching the plasma stream rapidly.
12-Stage Series Arc Splitting: Subdivides the single high-energy arc into 13 series short arcs, multiplying electrode voltage drops to exceed circuit recovery voltage for fast current limitation.
High Magnetic Lorentz Intake: Q195 cold-rolled steel generates strong magnetic permeability, quickly driving the arc roots off the moving contact into the de-ion stack.
Dimensionally Stable Integration: The single-piece glass fiber reinforced bracket maintains strict slot pitches during automated high-speed assembly and withstands severe mechanical shock without distortion.
Q1: What are the advantages of an integrated PA66-GF30 bracket over separate side boards in MCBs?
A1: An integrated PA66-GF30 bracket offers higher dimensional consistency, simplifies automated insertion on modular MCB assembly lines, and releases organic deionizing gas upon arc contact to speed up zero-crossing extinction.
Q2: Why choose Q195 cold-rolled steel with 2μm nickel plating for miniature breakers?
A2: Q195 steel offers optimal stamping precision for intricate V-notches and strong magnetic draw. The 2μm nickel layer prevents contact spot welding, resists environmental corrosion, and maintains thermal conductivity over repeated trip operations.
Q3: Can HAIPART customize the mounting dimensions and plate counts?
A3: Yes. We support complete OEM/ODM customization for miniature circuit breaker manufacturers, including runner contours, plate counts, thickness options, and bracket profiles.
