FAQs
This MCCB uses a plug‑in 3P connection designed for quick replacement in 690 V panels. Ensure correct current rating (20 A), secure mounting, and tight terminal torque per the Installation Instructions XT2, then verify the Rated Operational Voltage and clearances. Use compatible enclosures and follow applicable safety standards (IEC 60947‑2) to minimize downtime during commissioning and maintenance.
Key ratings include Rated Current In of 20 A, Rated Operational Voltage Ui of 1000 V, and Rated Operational Voltage Ue of 690 V AC / 500 V DC. Short‑circuit performance targets provide Ics up to 100 kA at lower voltages (e.g., 220–240 V) and up to 70 kA at higher voltages (e.g., 380–690 V). Uimp is 8 kV, with Iu listed at 160 A and a 3P configuration.
Yes. The unit carries a CE Declaration of Conformity for Tmax XT, along with RoHS information and a REACH declaration for ABB Sace circuit breakers. CMRT is provided for conflict minerals reporting, and WEEE packaging disposal information is available, supporting global regulatory compliance and sustainable procurement practices.
Release MA indicates the standard motor‑control friendly trip mechanism used in the XT2 family. It delivers reliable, repeatable tripping characteristics (Release M) with the ATLAS‑level reliability noted in the XT2 specification, helping ensure consistent protection for motors and feeders in automation environments and simplifying coordination with upstream protective devices.
Electrical durability is rated at 8000 cycles (120 cycles per hour), and mechanical durability at 25000 cycles (240 cycles per hour). This translates to predictable maintenance intervals, reduced unplanned downtime, and a favorable total cost of ownership when used in continuous production lines and automated systems.
