ABB 1SDA055055R1 Accessory for Tmax T - External Neutral
Part Number: 1SDA055055R1
Quick Summary
ABB 1SDA055055R1 is an external neutral accessory for Tmax T switchgear, rated at 320 A. It enables a robust neutral path in space-constrained panels, helping maintain circuit integrity and fault containment. Engineers often wrestle with compatibility gaps when sourcing spare parts for legacy Tmax T configurations, risking inconsistent performance and extended downtime. This accessory ships with clear compliance documentation, including REACH and RoHS declarations, CMRT reporting, and TSCA conformity, supporting global procurement requirements. By providing a reliable, IEC-aligned connector solution, it reduces install time, lowers the risk of neutral misconnection, and improves system reliability. In practice, it pairs with Tmax T assemblies to streamline field installations and maintenance workflows, delivering predictable, compliant operation.
