High-Performance GPO-3 Insulated Arc Extinguishing Chamber for MCCB

In industrial and commercial electrical systems, Molded Case Circuit Breakers (MCCB) require instantaneous arc quenching to suppress peak fault energy and preserve contact life. The 3012046 MCCB Arc Chamber combines high-permeability magnetic splitters with high-grade GPO-3 flame-retardant composites to deliver reliable short-circuit interruption.

Featuring an optimized 13-plate grid configuration stamped from premium 10# cold-rolled carbon steel (finished with a 1μm protective nickel layer) and supported by rigid, red GPO-3 glass mat boards, this unit achieves outstanding track resistance (CTI ≥ 600V) and millisecond arc deionization.

Side Wall Support	GPO-3 Unsaturated Polyester Glass Mat Board (CTI ≥ 600V, flame retardant, zero tracking)

Engineering Advantages & Extinguishing Principles

Superior Anti-Tracking (GPO-3): GPO-3 composite delivers exceptional resistance to carbon tracking under severe arc exposure, preventing electrical breakdown between poles.
Electromagnetic Arc Inflow: High-grade 10# carbon steel provides reliable magnetic permeability, rapidly pulling the arc off the moving contact into the splitter stack.
13-Stage Arc Splitting: Subdivides the single high-temperature arc into 14 series short arcs, multiplying the near-electrode voltage drops and accelerating zero-crossing extinction.
Robust Shock Absorption: The glass-mat reinforced polyester structure resists extreme acoustic and mechanical blowout forces during high-current short-circuit events.

Frequently Asked Questions (FAQ)

Q1: What are the key advantages of GPO-3 boards over standard insulation materials?

A1: GPO-3 is an alkali-free glass fiber mat impregnated with unsaturated polyester resin. It offers high flame retardancy (UL94 V-0), extreme arc resistance (>180 seconds), and an outstanding Comparative Tracking Index (CTI ≥ 600V), preventing conductive carbon path buildup.

Q2: Why use 10# carbon steel for the arc splitter plates?

A2: 10# steel offers balanced mechanical rigidity, high magnetic permeability, and excellent stamping stability, ensuring clean grid edges and precise plate gaps under thermal shock.

Q3: Can HAIPART provide custom modifications for specific MCCB casing dimensions?

A3: Yes. We offer comprehensive OEM/ODM engineering, accommodating custom plate counts, slot profiles, mounting lugs, and side board contours according to your exact mechanical drawings.
