Arc Chamber
HAIPART
3012047
For compact Molded Case Circuit Breakers (MCCB), rapid deionization in limited pole spaces requires both electromagnetic splitting and dynamic gas ablation. The 3012047 MCCB Arc Chamber integrates cold-rolled carbon steel splitters with gas-generating HB-77 insulating paper side boards and an arc-guiding shield to deliver high-velocity arc suppression.
Configured with a precision 13-plate de-ion grid stack stamped from high-permeability 10# steel (with 1μm anti-corrosion nickel plating) and reinforced by dual HB-77 vulcanized insulating boards, this arc chute generates immediate gas blast pressure upon arc ignition, rapidly cooling the plasma and preventing restrikes.
| Product Part Number | 3012047 (MCCB De-ion Arc Chute) |
| Structural Configuration | 13 De-ion Splitter Plates + 2 Support Side Boards + Arc Runner Hood |
| Grid Plate Material | 10# Cold-Rolled Carbon Steel (High magnetic saturation & stable arc suction) |
| Surface Electroplating | 1μm Precision Nickel Coating (Anti-oxidation & arc wear resistance) |
| Side Wall Support | HB-77 Vulcanized Insulating Paper (High arc quenching gas release & dielectric strength) |
Ablative Gas Quenching (HB-77): Under intense electric arc heat, the HB-77 vulcanized insulating paper instantly generates neutralizing organic gas blasts, rapidly blowing away ions and compressing the arc column.
Directional Arc Guiding: The front-fitted arc runner hood rapidly pulls arc roots away from breaker contacts, guiding plasma safely along the 13-stage splitter stack.
13-Stage Arc Sub-Division: Divides the single main fault arc into 14 series short arcs, multiplying electrode voltage drops to exceed the recovery voltage for fast current limitation.
Cost-Effective & Reliable: Combining 10# carbon steel grids with vulcanized fiber offers balanced mechanical resilience and cost performance for mass OEM switchgear manufacturing.
Q1: What are the distinct properties of HB-77 insulating paper in arc chutes?
A1: HB-77 is a specialized vulcanized insulating paper board engineered for circuit breakers. Upon contact with the electric arc, it releases non-conductive deionizing gas that builds localized pressure, actively cooling and blowing out the plasma stream.
Q2: What is the purpose of the front metal guide plate on this model?
A2: The front runner hood serves as an arc ignition catcher, shielding internal components and creating an immediate electromagnetic draw that forces the arc root to commutate off breaker contacts into the splitter chamber.
Q3: Can HAIPART customize the mounting dimensions and plate counts?
A3: Yes. We support complete OEM/ODM customization for molded case breaker manufacturers, including runner contours, plate counts, thickness options, and side board profiles.
