125A Distribution Box Dimensions and Specifications

A typical 125A single-phase distribution box usually measures around 400–600 mm in height, 300–500 mm in width, and 150–250 mm in depth, depending on the model and manufacturer.

General Overview125

A distribution boxes are designed for residential, commercial, and light industrial applications. They provide safe and reliable power distribution, often including features such as: DIN rail mounting for circuit breakers and terminal blocks Metal or plastic enclosures for durability and electrical safety Modular configurations to accommodate multiple circuits, fuses, or differential switches Customizable options including emergency stop switches, various socket types, and grounding terminals Typical DimensionsWhile exact dimensions vary by manufacturer, common ranges for a 125A single-phase distribution box are: Height: 400–600 mmWidth: 300–500 mmDepth: 150–250 mm For example, industrial-grade plug-in modular boxes (like the CH12L125F) are designed for indoor applications and may fall within these ranges.

Smaller residential models may be more compact, while larger worksite or industrial cabinets can be taller and deeper to accommodate additional circuit breakers and accessories.

Installation Considerations

Ensure sufficient clearance around the box for wiring and maintenance.

Check DI

N rail compatibility (typically 35 mm) for mounting breakers and terminal blocks.

Verify I

P rating for protection against dust and moisture, especially in industrial or outdoor environments. For precise dimensions, it is recommended to consult the manufacturer's datasheet for the specific 125A distribution box model you plan to install, as features and sizes can vary significantly.
