DC protection with a 63 A rated current and 4P configuration delivers robust safeguarding of DC distribution in automation panels, while front-terminal wiring simplifies installation and future maintenance, reducing cabinet complexity. The thermomagnetic release (TMA TM) provides fast, reliable tripping for short-circuit events, supporting up to 36 kA breaking capacity in the specified configurations, which translates to minimized downtime and protection for sensitive drives and power buses. With 25,000 mechanical cycles durability, the device is built for frequent operation in dynamic manufacturing environments, delivering consistent performance and extended service life. Low power loss of 4.85 W per pole improves overall system energy efficiency, contributing to lower operating costs in high-availability plants. Sustainability features include an EPD (CN), 55.7% recyclability per EN45555, RoHS/REACH compliance, and end-of-life disassembly guidance, aligning with modern corporate responsibility programs. The MCCB adheres to IEC 60947-2 and GB/T 14028.2 standards, ensuring compatibility with global panels and a wide range of ABB EcoSolutions initiatives. Built as part of the Tmax XT2 family, it offers reliable protection for DC buses in servo drives, battery storage interfaces, and other critical loads, while streamlining commissioning thanks to standardized mounting and wiring practices.

FAQs
Ensure correct mounting clearance and panel space for a 4P MCCB. Connect each of the four front terminals with appropriate torque as specified in the XT2 DC installation instructions. Verify polarity and ensure the device is fully seated in its fixed-circuit-breaker enclosure. Use the TM release to confirm proper tripping behavior during a test.
The device provides a rated service short-circuit breaking capacity (Ics) of 36 kA for 250 V DC when configured as two poles in series, and 36 kA for 500 V DC when configured as three poles in series. The rated ultimate short-circuit breaking capacity (Icu) matches these values, ensuring strong protection for high-energy DC systems.
Yes. With 4P configuration, DC operation up to 500 V, 63 A nominal current, and TM/TMA thermomagnetic release, this MCCB is well-suited for DC buses in servo drives, motor drives, and energy storage interfaces where fast interruption and reliable protection are critical for uptime and equipment longevity.
It complies with IEC 60947-2 and GB/T 14028.2, and carries CE conformity (EC Declaration of Conformity). Supporting documentation includes installation instructions XT2 DC IEC and environmental declarations like EPD (CN), RoHS, REACH, and end-of-life information under EN45555.
With a mechanical durability rating of 25,000 cycles and a modest 4.85 W power loss per pole, it reduces wear and energy costs in frequent switching scenarios. Front-terminal design and fixed mounting simplify maintenance and replacement, lowering downtime and contributing to lower total cost of ownership in high-availability DC networks.
