ABB Expands EH3 Outdoor Enclosures and Introduces CombiLine MP Interior Fittings at Light + Building 2026
16/03/2026 ABB Limited (Zurich)
- Larger 1,310 mm EH3 outdoor enclosure option supports increased component density driven by electrification and renewable energy integration
- CombiLine interior fitting system now available for mounting plate applications, extending 40 years of installation efficiency[AL1] [AK2] to outdoor enclosure configurations
- New wire holder accessories manufactured from recycled plastics double cable capacity while reducing installation time
ABB is unveiling significant enhancements to its EH3 outdoor enclosure portfolio – GRP (Glass Reinforced Polyester) cabinets for energy distribution and cable management – alongside the new CombiLine interior fitting system at Light + Building 2026. The larger enclosure sizes and integrated mounting plate solution address the growing complexity of modern electrical infrastructure, as electrification, renewable energy integration and intelligent energy management increase both the number and size of components housed within outdoor enclosures.
Expanded Enclosure Capacity Addresses Evolving Infrastructure Requirements
ABB has introduced a new 1,310 mm height option for its EH3 outdoor enclosure series, complementing the existing 875 mm and 1,125 mm configurations. The larger enclosure option provides greater flexibility as electrical infrastructure evolves beyond traditional distribution requirements.
Outdoor enclosures are increasingly required to accommodate power distribution components, as well as metering devices, communication modules, and energy management systems within a single protected environment. Applications such as residential distribution networks, supermarket installations and solar-integrated parking facilities with electric vehicle charging require more space within the enclosure, as both the number and size of components continue to increase.
The EH3 series provides IP-rated protection suitable for demanding outdoor environments, featuring vandal-resistant locking mechanisms and sloped roof designs that prevent water and debris accumulation. The enclosures incorporate stable mounting points for busbars and are engineered to withstand exposure to sun, rain, and road salt.
CombiLine MP Extends Interior Fitting to Mounting Plate Applications
ABB has also introduced CombiLine MP, extending its established 40-year CombiLine interior fitting system to mounting plate applications commonly used in outdoor enclosures such as EH3. CombiLine MP utilizes a modular architecture based on EDF profiles, supporting meter, current transformer, and distribution applications up to 440 A. CombiLine MP combines lower and upper mounting elements that can be configured to suit specific application requirements, enabling structured component arrangements even in space-constrained installations.
Front cable entry through the lower mounting element simplifies installation, while an IP54-rated meter hood provides splash protection for both indoor and outdoor use. The modular design maintains accessibility for maintenance and future modifications.
