Feature → Business Impact → Application: 1) Three-pole TMF release with front terminals enables quick wiring and reliable venting, reducing installation time in crowded control panels and minimizing miswiring risk in high-density switchgear environments. This translates to lower labor costs and faster panel commissioning for new builds and retrofits in manufacturing lines. 2) Rated current of 50 A and adequate Iu of 125 A provide strong protection for main feeders while maintaining acceptable voltage drop in general industrial power distribution, improving system availability in continuous operation environments such as packaging or automotive assembly lines. 3) Short-circuit performance up to 50 kA (Ics at 240 V AC) and 36 kA (Icu at 380–415 V AC) deliver dependable fault interruption for transformer-fed systems, enabling safer shutdowns and reducing arc-flash exposure during faults in medium-voltage distribution. 4) High insulation voltage Ui of 690 V and rated impulse withstand 6 kV support safe operation in mixed AC/DC feeder configurations common in modern plants, enhancing protection in mixed-signal and power environments. 5) Electrical durability of 1500 cycles and mechanical durability of 8500 cycles offer predictable lifecycle performance in high-usage panels, delivering lower maintenance costs and fewer replacements over time. 6) Compact dimensions with a net width of 76.2 mm, height 130 mm, and depth 60 mm support denser panel layouts and easier retrofits, improving overall cabinet economics for OEMs and integrators. 7) Product data and compliance documentation, including RoHS/REACH declarations and CE declarations, streamline regulatory audits and supplier qualification for global projects. 8) Compatibility with standard wiring diagrams and installation instructions (Wiring Diagram FORMULA A1-A2; Installation Instructions Formula A1/III-IV) reduces ambiguity during installation and accelerates commissioning in diverse industrial environments.

FAQs
This unit uses front-terminal connections, which simplifies wiring in tight panel spaces and reduces risk of cross‑contact during assembly. Its 3P configuration and compact footprint (76.2 mm wide, 130 mm high, 60 mm deep) fit standard DIN rail or screwed mounting in industrial panels. Ensure proper labeling and adherence to the Wiring Diagram FORMULA A1-A2 to maintain clear traceability for maintenance and regulatory audits.
The breaker is rated for 50 A main current with a rated insulation voltage of 690 V and a rated operational voltage up to 550 V AC / 250 V DC. It offers a 6 kV impulse withstand and short-circuit breaking capacities of up to 50 kA (Ics at 240 V AC) and 18–7.5 kA across higher voltages (380–500 V AC). Release is TMF with a 3P front connection, delivering reliable protection in transformer or generator feeder circuits and enabling safe disconnection under fault conditions.
Yes. The product carries a REACH declaration, RoHS information and RoHS status aligned with EU Directive 2011/65/EU and Amendment 2015/863, and a CE Declaration of Conformity for Formula A1. These certifications simplify regulatory approvals, supplier qualification, and global market access for industrial equipment installed in factories, utilities, and infrastructure projects.
Electrical durability is rated at 1500 operating cycles and mechanical durability at 8500 operations, with a rated uninterrupted current of 125 A. This combination supports long service life in high-demand environments, reduces unscheduled maintenance, and lowers replacement costs for critical feeders and distribution panels in continuous‑operation facilities such as automotive lines or process industries.
Ideal for power distribution in industrial panels, transformers, and generator protection where reliable 3P protection is essential. As part of ABB SACE Formula, it offers a front-terminal design, TMF release, and strong Ics/Icu ratings that balance protection with compact form factor. Compared with alternatives, this MCCB delivers robust compliance (IEC, CE, RoHS) and a predictable lifecycle, making it a strong choice for OEMs seeking efficient installation and lower maintenance costs in high‑volume manufacturing or utility installations.
