Metal Power Distribution Box For Factories, Home, Industries, Mills, Commercial

a **power distribution box** (also known as a distribution board or panel) is used to distribute electrical power to various circuits in a building or facility. it houses circuit breakers, fuses, or switches for circuit protection. the ratings for power distribution boxes depend on their application and capacity. here are typical ratings:

1. **current ratings**:

   - **standard ratings**: **63a, 100a, 125a, 250a, 400a, 630a, 800a, 1000a, 1600a, 2500a**

   - used in residential, commercial, and industrial applications depending on the power requirements.

2. **voltage ratings**:

   - **single-phase**: **230v/240v**

   - **three-phase**: **400v/415v**

3. **number of ways (circuits)**:

   - **2-way to 24-way** (common in residential systems)

   - **up to 48-way or more** (for larger commercial/industrial installations)

4. **short-circuit withstand capacity**:

   - typically ranges from **10ka to 50ka**, depending on the application.

5. **ingress protection (ip ratings)**:

   - **ip30 to ip65**, depending on indoor or outdoor installation.

these ratings ensure proper selection based on the load and safety requirements of the electrical system.
