Feature → Interior fitting module tailored for CombiLine panels provides a compact 24 DIN-place footprint, reducing cabinet width without sacrificing accessibility. This improves maintenance turnaround and spare-part planning by letting you pre-plan one device in a dedicated 500 mm wide slot. Feature → 4P, 125 A rating with 400 V operation ensures reliable isolation of all poles, supporting safe startup and shutdown of multi‑line drives in industrial panels. This translates to lower fault exposure and faster commissioning in grid-tied systems. Feature → Frame compatibility with WR or EDF mounting frames offers flexible installation in a range of cabinet configurations, enabling streamlined retrofits and standardised layouts across facilities. This reduces total cost of ownership by simplifying sourcing and field assembly. Feature → RoHS and REACH compliance plus CE declaration provide regulatory assurance for European projects, minimizing risk during audits and customer inspections. This supports compliant procurement and smoother handovers to operations. Feature → Documentation and installation support, including MBA125ALT mounting instructions, improves first-time fit and reduces service time, helping technicians complete panel builds with confidence.
