FAQs
This device uses fixed front terminals designed for easy wiring access in compact control cabinets. It fits standard XT2L DC protection schemes and is compatible with 4-pole configurations typical in DC power distribution within industrial automation panels. When wiring, ensure correct polarity awareness and maintain clearances per IEC 60947-2 guidelines to preserve tripping performance and electrical clearance.
The 1SDA123553R1 delivers up to 85 kA short-circuit capacity for both service and ultimate ratings in 2- or 3-pole series under 250 V DC or 500 V DC conditions, with a rated service current of 20 A and uninterrupted current of 160 A. These specs support reliable fault interruption and safe operation in demanding DC distribution applications.
Yes. The unit provides RoHS compliance and REACH declarations for ABB Sace circuit breakers, with an Environmental Product Declaration (EPD) for Tmax XT XT2 TM and recyclability data aligned to EN45555. This supports regulatory compliance, responsible sourcing, and sustainability reporting in procurement processes.
Mechanical durability is rated at up to 25,000 cycles, with a specified cycle rate of about 240 cycles per hour. This makes the breaker well-suited for frequent operation in automated lines and robotics where frequent switching occurs, while maintaining precise protection thresholds and reliable trip performance.
Ideal for DC power distribution in industrial automation, particularly in ABB Tmax XT2L ecosystems. It supports front-terminal wiring, 4P protection, and robust short-circuit performance, making it suitable for panels in manufacturing, material handling, and process automation where reliable DC protection, fast serviceability, and regulatory compliance are essential.
