# Industrial Specification: Chamber Housing

## 1. Technical Definition
The structural enclosure that contains and supports the arc extinguishing components within an arc chute or circuit breaker.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-40 bar internal pressure, -40°C to 150°C temperature**. Failure boundary: **45 bar internal pressure causing plastic deformation, 180°C temperature causing glass transition of polymer composites**, Mechanism: **Von Mises yield criterion exceeding 250 MPa yield strength of 6061-T6 aluminum, polymer matrix degradation at glass transition temperature**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.
