Front-terminal design enables quicker, safer wiring and reduced installation time, translating into lower labor costs and fewer field errors while maintaining secure, durable connections in dense cabinet layouts. The thermomagnetic TMF release provides precise protection coordination and fast fault isolation, minimizing damage to downstream equipment during peak fault conditions and helping you meet uptime targets in critical processes. With a rated current of 15 A, rated insulation voltage of 690 V, and an impulse withstand of 6 kV, this MCCB delivers robust electrical integrity across standard industrial environments, supporting reliable operation in both AC and DC sections. Electrical durability of 1500 cycles and mechanical durability of 8500 cycles ensure long service life with predictable maintenance planning and reduced replacement spend. Compliance with IEC standards, CE marking, and RoHS/REACH declarations reduces regulatory risk and simplifies audit processes. Low power loss per pole (2.5 W) improves overall energy efficiency in continuous-distribution applications. The compact front-access design, 3P configuration, and 1SDA Formula family compatibility enable quick retrofits and seamless integration into existing ABB or third-party protection schemes, reducing panel downtime during upgrades and replacements. This model is well-suited for transformer protection, generator interfaces, and motor-control centers in medium to large industrial facilities where predictable performance and serviceability are critical.

FAQs
Install the 1SDA066721R1 using standard front-terminal wiring practices. Ensure correct torque on terminals, route conductors to prevent contact with moving parts, and follow the 136.5 mm width and 60 mm depth envelope to maintain clearance. The 3P configuration fits typical MCCB slots, and the TMF release is designed for straightforward integration with existing protection schemes.
The unit is rated for In = 15 A, Ui = 690 V, Uimp = 6 kV, and offers service short-circuit current Ics up to 50 kA at 240 V, 18 kA at 380 V, 7.5 kA at 415 V, and 6.25 kA at 440 V. It also provides Icu values up to 100 kA at several voltages and a rated operating voltage of 550 V AC / 250 V DC.
Yes. The device conforms to IEC standards and carries a CE declaration of conformity. It also aligns with RoHS/REACH requirements and TSCA documentation, supporting regulatory compliance for global manufacturing and installation programs.
TMF refers to the thermomagnetic release used in this A1 sub-type. It provides a combination of thermal and magnetic tripping for reliable coordination under overloads and short circuits. Use it in panels where fast fault clearing and robust motor or transformer protection are required, ensuring consistent trip behavior across the 3P circuit.
Electrical durability is rated at 1500 cycles and mechanical durability at 8500 cycles, indicating a long service life with predictable replacement intervals. Regular inspections should verify terminal integrity, verify trip timing, and confirm front-access wiring remains secure to maintain reliable protection and minimize unplanned maintenance events.
