How much is a 315 distribution box

A 315-module distribution box typically costs between €43 for a basic small unit and several thousand euros for a fully equipped industrial-grade metal box.

Pricing Overview

Basic small distribution boxes: For example, the ST25 315 distribution box (300x250x150mm, IP66) is available for €43. 46 through online stores like Vikiwat, suitable for smaller or residential applications. Flush-mounted metal boxes for 315 modules: Larger, steel-built, flush-mounted units with IP30 protection and capacity for 315 modules, such as the Eaton BP-U-3S-MES-800/15-ST, are designed for industrial or commercial use.

These units are significantly more expensive, often costing several hundred to over a thousand euros, depending on included switchgear, DIN rails, and protective devices.

Factors Affecting Cost

Material and Construction: Steel or stainless steel enclosures are more durable and costly than plastic or basic metal units. Protection Rating: Higher IP ratings (e.g., IP66) for outdoor or harsh environments increase the price. Internal Components: Pre-equipped boxes with circuit breakers, residual current devices, and surge protection are more expensive than empty shells.

Customization: Options like modular DIN rails, smart monitoring, or integration with building management systems can raise costs. Installation and Location: Shipping, installation complexity, and local regulations can influence the total investment.

Summary

For a residential or small commercial setup, a 315 distribution box can start around €40–€50 for a basic unit. For industrial or large-scale applications, fully equipped metal boxes with 315-module capacity can cost hundreds to thousands of euros, depending on specifications, protection level, and included components. Always consider long-term durability, safety, and compliance with local electrical codes when selecting a distribution box.
