Feature → Business Impact → Application: 4P XT2 mold with Ekip LSI release delivers precise trip management and rapid fault isolation, reducing arc energy exposure and improving personnel safety in metal-enclosed switchgear. In practice, this means fewer nuisance trips during transient faults and a predictable protection strategy for distribution boards in manufacturing lines. Application: motor control centers and power distribution panels requiring robust AC protection. Feature → Business Impact → Application: Rated 100 A at 50/60 Hz and 690 V AC supports wide input ranges and future expansion; coupled with a low power loss of 4.20 W per pole, it minimizes heat build-up and cooling requirements, lowering energy costs in hot environments. Application: high-availability racks and transformer stations. Feature → Business Impact → Application: Front terminal connection and 6 N·m tightening torque simplify wiring, speeding up installation and improving reliability in tight control panels, especially where space is at a premium. Application: compact switchgear and retrofit projects. Feature → Business Impact → Application: Busbar connection capability up to 32.5–100 mm² enables flexible wiring schemes and reduces the need for adapters; Application: industrial facilities upgrading feeders or expanding distribution without reconfiguring busbars. Feature → Business Impact → Application: Disassembly and environmental guidance under ABB EcoSolutions supports sustainable lifecycle management; Application: facilities pursuing waste-to-landfill reductions and end-of-life planning. Feature → Business Impact → Application: RoHS and REACH declarations ensure regulatory compliance for European and global supply chains; Application: regulated industries such as chemical, HVAC, and energy distribution where compliance reduces risk and project delays.

FAQs
For panel installations, use the front-terminal design with 4P configuration and tighten to 6 N·m. Ensure busbar sizing between 32.5 and 100 mm² matches your supply, and space the device to allow access for maintenance. Also verify compatibility with Ekip LSI release and follow the installation instructions for XT2 variants to ensure correct trip settings.
Key ratings include 100 A rated current, 690 V AC rated operational voltage, and 50/60 Hz frequency. The short-circuit performance is defined under UL489 with a four-pole configuration. The device supports front-terminal connections and has a rated power loss of 4.20 W per pole under rated conditions, aiding thermal management in panels.
Yes. The XT2 four-pole MCB design with Ekip LSI release is intended for power distribution and protection of feeders to transformers and generators. Its 4P front-terminal arrangement and 100 A rating suit feeders in medium to large industrial installations, helping prevent motor and transformer faults from propagating through the network.
The breaker is UL489-listed and CSA-certified (Intrinsic Safe), with a CE declaration of conformity for Tmax XT2. It also carries RoHS and REACH declarations and a CMRT for conflict minerals. These certifications support global deployment while simplifying regulatory approvals and product stewardship programs.
With a compact 4P front-terminal design, minimal wiring complexity, and a modest heat loss of 4.20 W per pole, installation and cooling costs are reduced. The Ekip LSI release offers reliable protection with predictable maintenance cycles, and ABB EcoSolutions resources provide end-of-life guidance, contributing to lower lifecycle costs and easier compliance reporting.
