FAQs
Installation follows the System pro E power RBBS CH mounting instructions for copper connections, including CT mounting steps and the XT7/E1.2W 1600A/2000A guidelines. Ensure proper torque, alignment with bus bars, and secure clamping at all four poles. Verify compliance with on-site grounding and enclosure clearances before power-up.
The terminal supports a 1250 A rating in a 4-pole configuration (4P) with XT7/E1.2W copper connections. It corresponds to D8/1 and P3 mechanical references in ABB documentation and is intended for high-current distribution in switchgear and bus systems.
Yes. The design targets copper connections for bus systems and aligns with ETIM EC000635 and eClass 27143105 classifications, indicating suitability for connection/branching terminals in power distribution networks. It is optimized for reliable performance in demanding industrial switchgear environments.
WEEE Category is 4 Large Equipment, with B2B applicability. REACH information states no substances above 0.1 mass percentage. The Environmental Declarations include NoDecNee, and packaging/disposal guidance is provided under ABB environmental information. These data points facilitate regulatory reporting and sustainability benchmarking.
The high-current copper connection and robust mechanical design reduce contact resistance and heat, lowering maintenance intervals and failure risk. Clear installation guidance and standardized interfaces shorten commissioning, while packaging and disposal information streamline audits and logistics, contributing to lower total cost of ownership over the equipment lifecycle.
