Key Benefits

Benefit pictogram

Reliable in extreme conditions

System pro E power switchboards are fully certified according to IEC 61439-2 through rigorous testing covering all the configurations. Anti-seismic certification up to a peak of 3g ZPA and passive arc fault protection up to Class A ensure operator safety in the most demanding environments.

Benefit pictogram

Scalability

System pro E power delivers unmatched configuration flexibility for evolving projects. Its modular architecture enables infinite configurations, positioning breakers and busbars exactly where needed.

Benefit pictogram

Footprint optimization

Maximize your installation footprint with configurations modularity, designed to meet diverse project requirements. System pro E power enables optimal space utilization by housing multiple air-circuit breakers within a single panel, even within a compact 400mm wide column.


Tested & Certified

The System pro E power TBBS certificate consolidates all rigorous tests and corresponding performance metrics into a single comprehensive document. It covers all the portfolio configurations, including conductors and the full portfolio of ABB Circuit Breakers. 
Certified according to IEC 61439-2 standard.

ABB Enclosure, Main Distribution Board & Switchboard Icon - Anti-Seismic Benefit

Anti-seismic withstand

To ensure switchboard stability in seismic zones, System pro E power is seismic certified up to 1g and 3g peak ZPA. Our rigorous 40-second test ensured full switchboard operation during and after seismic events, with all electrical and mechanical characteristics — including IP and IK protection ratings — maintained. This comprehensive testing guarantees reliable performance when it matters most.

ABB Enclosure, Main Distribution Board & Switchboard Icon - Arc Fault Protection Benefit

Passive arc fault solution

Arc fault protection up to Criteria 1-5/Class A, certified according to IEC TR 61641, is provided by opening flaps on the roof. In the event of an internal arc fault, the flaps open automatically to safely release hot gases upward, preventing pressure buildup in the front functional area and protecting operators and assets.
