ABB 1SDA054663R1 Accessory - 4P Thermomagnetic Release

The four-pole thermomagnetic release (TMA) inside 1SDA054663R1 delivers precise overcurrent protection for Tmax T systems. Rated at 80 A (I_n), this device maintains fast response during short circuits while suppressing nuisance trips. Business impact: sharper protection coordination reduces motor and feeder damage, shortening downtime and extending equipment life. Application: ideal for SACE Tmax T installations in manufacturing lines and critical distribution panels requiring reliable four-pole protection. Compliance and declarations underpin risk management and procurement confidence. The unit supports RoHS information, REACH declarations, and CE conformity, with TSCA considerations documented and available. Documentation includes a CE Declaration of Conformity (1SDL000165R0001) and data sheet (1SDC210015D0201), helping engineering teams qualify, test, and maintain the device with minimal rework. CMRT availability on demand further enhances supply-chain transparency and sustainability reporting, which is valuable for regulated industries and global sourcing programs. Configuration and installation are streamlined by loose or configurable mounting options and full Tmax T compatibility. The 4P 80 A accessory integrates into standard panel architectures, reducing spare-parts variety and accelerating commissioning. With easy wiring, field configuration, and documented setup, engineers can shorten project timelines and achieve repeatable protection schemes across multiple panels. Reliability and uptime are improved through a robust thermomagnetic trip unit that delivers consistent coordination during overload and short-circuit conditions. The compact footprint (1 kg net, 1.1 kg gross) and packaging (158 x 158 x 188 mm) simplify inventory and installation, while the EC classification and ETIM alignment support accurate parts data in maintenance systems.
