Product Main Type
ReliaGear UL891
High-current rating and robust protection → Reduces the need to oversize protection devices, freeing space and lowering material costs while delivering rapid fault isolation. This translates to measurable uptime gains for data centers and continuous manufacturing lines, where a 4000A capability supports heavy load profiles and fault-clearing reliability. Application-wise, it fits demanding industrial environments requiring dependable high-current circuit protection and scalable installation across multiple switchgear configurations. UL891 ReliaGear platform compatibility → Seamless integration with existing ABB switchgear, familiar mounting patterns, and consistent wiring practices. Business impact includes reduced installation time, fewer wiring errors, and simpler spare-part planning, which lowers total cost of ownership. This is particularly advantageous during panel retrofits or new-build projects in automation, process industries, and mission-critical facilities. Regulatory compliance with REACH and WEEE alignment → Ensures environmental and regulatory reporting requirements are met, with REACH Information showing no substances above thresholds and WEEE Category indicating non-scope status. Business value is continuity in global sourcing and easier lifecycle stewardship. Applications span global manufacturing, data-center upgrades, and utility-scale projects needing compliant electrical protection solutions. Clear labeling and documentation → Accelerates maintenance activities and fault diagnosis by providing unambiguous indicators and reference materials. The operational impact is shorter mean time to repair and reduced training time for field technicians. This supports service teams in industrial facilities, campuses, and multi-site deployments where rapid, accurate maintenance is essential. Reliability and environmental resilience → Built for steady performance under varying conditions, minimizing unexpected outages and extending intervals between preventive maintenance. The resulting ROI emerges as lower lifecycle costs, improved asset utilization, and enhanced protection for critical loads across manufacturing and data-center environments.
