Arc Chamber
HAIPART
3012054
In industrial low-voltage distribution and power switching equipment, Molded Case Circuit Breakers (MCCB) demand instantaneous fault arc suppression to minimize contact ablation and let-through energy. The 3012054 MCCB Arc Chamber combines magnetic steel splitters, rapid heat-dissipating copper plating, and tough vulcanized fiber structural side walls to provide reliable short-circuit protection.
Configured with a 14-plate de-ion grid array stamped from high-permeability 10# cold-rolled steel (finished with a 1μm copper electroplating layer) and supported by dual vulcanized red fiber boards, this arc chute delivers fast arc commutation, multi-arc voltage buildup, and resilient mechanical containment.
| Product Part Number | 3012054 (MCCB De-ion Arc Chute) |
| Structural Configuration | 14 De-ion Splitter Plates + 2 Support Side Boards |
| Grid Plate Material | 10# Cold-Rolled Carbon Steel (Superior magnetic suction & mechanical strength) |
| Surface Electroplating | 1μm Precision Copper Plating (High thermal dissipation & rapid arc spot diffusion) |
| Side Wall Support | Vulcanized Red Fiber Board (Red steel paper: high mechanical flexibility & arc resistance) |
Rapid Heat Dissipation via Copper Layer: The 1μm copper coating rapidly draws localized thermal energy away from the arc root, preventing steel grid ablation and contact welding.
14-Stage Serial Arc Splitting: The 14-plate grid array cuts the single primary fault arc into 15 serial micro-arcs, establishing an immediate cumulative near-electrode voltage drop that rapidly forces zero-crossing extinction.
Shock-Resistant Red Fiber Walls: Vulcanized red fiber provides excellent tensile flexibility and acoustic shock dampening, absorbing violent magnetic burst forces without shattering.
Magnetic Inflow Induction: The high-permeability 10# steel substrate generates strong electromagnetic Lorentz forces that quickly draw the plasma column deep into the splitter slots.
Q1: What are the unique characteristics of Vulcanized Red Fiber (Red Steel Paper) side boards?
A1: Vulcanized red fiber is an exceptionally tough cellulosic composite. Under high-energy electric arcs, it maintains superior impact resistance, resists cracking under electromagnetic pressure waves, and releases trace cooling vapors that facilitate plasma deionization.
Q2: Why combine 10# steel plates with copper plating rather than nickel?
A2: While nickel excels at extreme chemical corrosion resistance, copper provides superior thermal conductivity. This allows for faster dissipation of concentrated arc heat across the grid surface, which significantly shortens arcing duration.
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.
