Power distribution boxes in Finland vary by type and application, with typical compact units around 400–850 mm in height, 300–500 mm in width, and 150–300 mm in depth.

Typical Sizes

• Compact worksite distribution boxes: For example, the TAS16/1/K model is a Finnish-made compact housing unit designed for 16A circuits. While exact dimensions are not listed in the source, similar worksite boxes generally measure approximately 400–500 mm high, 300–400 mm wide, and 150–200 mm deep .
• Standard distribution cabinets: Larger cabinets used for network or industrial applications, such as the Dist.Cabin. K0 850 300P LT5090, indicate dimensions in the model code: 850 mm height, 300 mm width, with depth typically around 200–300 mm .
• Residential breaker panels: Indoor residential distribution boxes in Finland usually range from 400–600 mm in height, 300–400 mm in width, and 150–200 mm in depth, accommodating 12–42 circuits depending on the panel type .
• Industrial and medium-voltage panels: These are significantly larger, often exceeding 1,000 mm in height and 600 mm in width, with depths of 300–500 mm, designed to house multiple breakers, bus bars, and control equipment .

Considerations

• Voltage and phase: Low-voltage boxes (0.4–1 kV) are smaller, while medium-voltage cabinets (1–70 kV) are larger and often custom-built.
• Indoor vs. outdoor: Outdoor boxes are weatherproof and may include steel frames, increasing overall dimensions.
• Customization: Many Finnish manufacturers offer custom enclosures to fit specific industrial, renewable energy, or telecom applications . In summary, Finnish power distribution boxes range from compact worksite units around 400×300×150 mm to large industrial cabinets exceeding 1,000×600×500 mm, with exact dimensions depending on application, voltage, and number of circuits.
