Wide voltage range and flexible wiring enable easier installation and maintenance, reducing panel wiring errors and inventory costs while delivering reliable under-voltage protection across 24-30 V AC/DC controls. This translates to faster commissioning, fewer field faults, and improved uptime in critical power distribution. The T4-T5-T6 shunt release design ensures fast breaker opening during undervoltage events, enhancing system safety for motor and process loads in manufacturing and infrastructure environments. Loose or configurable configuration supports straightforward retrofits and modular upgrades without extensive cabinet rewiring, minimizing downtime and project risk. Compatibility with the Tmax T series simplifies spare parts management and procurement, while maintaining compliance with IEC standards and CE marking for global deployments. The accessory’s lightweight packaging (approx. 0.12 kg net) and standard packaging (1 piece per level) streamline stocking, while the 24-30 V range supports mixed-control architectures common in industrial plants. Environmental and material compliance (RoHS/REACH) ensures sustainable integration with modern automation schemes, reducing future retraining or redesign needs. The product’s country of origin (Italy) indicates established European manufacturing quality and traceability, adding confidence during supplier audits and long-term maintenance planning.

FAQs
The ABB 1SDA054870R1 is designed as an accessory for Tmax T power circuit breakers and supports loose or configurable installation. It operates on 24-30 V AC/DC and is compatible with T4, T5 and T6 shunt release configurations. When retrofitting, verify control wiring matches the 24-30 V range and ensure secure connections to prevent nuisance trips.
Key specifications include a rated voltage of 24-30 V AC or DC and a current type of AC/DC. Operating outside this range can lead to unreliable tripping or failure to open the circuit breaker during undervoltage events. For consistent protection, use the device within its stated voltage window and follow OEM wiring diagrams during installation.
Yes, the shunt release aligns with IEC standards and carries CE conformity. This ensures compliance with European safety and electrical testing norms, supporting regulatory acceptance in global installations. Maintain proper documentation for audits, including CE declarations and any relevant IEC test results referenced by ABB data sheets.
As with other Tmax T accessories, plan routine inspection of wiring connections, integrity of the control circuit, and verification that the release operates within the 24-30 V range. Since the product is an under-voltage release accessory, ensure compatibility with the current Tmax T configuration and replace if any mechanical or electrical signs of wear appear, following ABB’s service guidelines.
Adding the ABB shunt release improves protection against undervoltage events, reducing nuisance trips and unplanned downtime. It enables faster, controlled tripping of the Tmax T breaker, enhancing process safety and uptime. The compatibility with 24-30 V AC/DC controls simplifies wiring, lowers spare parts complexity, and supports compliant, scalable maintenance across mixed-control environments.
