ReliaGear UL891
High-current capability and the ReliaGear UL891 design deliver robust protection for congested feeders and critical buses. The 2500A N3R 1600A rating supports peak loads without oversized cabinets, reducing footprint and energy losses through optimized busbar integration. In data centers, manufacturing lines, and process facilities where uptime is essential, this translates to fewer unplanned outages and faster fault isolation. The modular architecture also eases future upgrades and simplifies spare-parts management, helping maintenance teams respond faster and keep production lines running. Installation-friendly features speed project timelines with standardized interfaces and straightforward wiring, compatibility with existing ABB protection schemes, and clearly labeled phases. Documentation-aligned BOMs and predictable torque specs reduce commissioning risk and field errors. Material compliance—REACH and WEEE—minimizes regulatory overhead, enabling smoother procurement and audits. Reliability, safety, and lifecycle cost are improved through easy component replacement and a scalable protection platform that supports plant standardization.
