ABB 1SDA081059R1 Moulded Case Circuit Breaker - 4P 8kV IEC
Part Number: 1SDA081059R1
Quick Summary
ABB 1SDA081059R1 is a Tmax T5S moulded case circuit breaker designed for protection in industrial power distribution. It provides reliable three- and four-pole protection with front terminals for quick wiring and service. Operators commonly face nuisance trips and downtime when protection devices lack selectivity and clear documentation, making maintenance costly. This model carries CE conformity (EC Declaration of Conformity), RoHS compliance, and REACH declarations, along with TSCA certification to support global supply chains. With 400 A rated current and a robust 4P configuration, it delivers dependable short-circuit protection for demanding motor loads and transformers, while the E-LSIG solid-state release improves trip accuracy. Documentation, ETIM/eClass classifications, and compatibility with SACE Tmax T accessories simplify procurement and installation for panel builders and integrators.

Front-terminal connection supports quick wiring and servicing, reducing installation time and minimizing wiring errors in crowded panel spaces. This 4P design delivers balanced protection across three-phase systems with a neutral, improving system reliability and safeguarding critical loads like motors and transformers. The Ekip E-LSIG solid-state release enhances trip accuracy and response consistency, translating into fewer nuisance trips and better coordination with other protective devices. Rated for 690 V AC and 1000 V insulation, it supports broad industrial applications while maintaining a compact footprint and straightforward retrofit compatibility with Tmax T5 components. The 400 A rating, 8 kV impulse withstand, and Ics/Icu specifications provide clear protection envelopes for both new builds and modernization projects. Compliance documentation and packaging details streamline procurement, auditing, and end-to-end traceability for regulated industries.
