Atlas Copco 1089941558 Contactor AX185-30-11 (3) Critical Applications & Core System Positioning This original component acts as a cornerstone in the electrical management architecture of heavy machinery. Regarding its exact system application, engineers utilize this high-capacity component within several key areas: 1. Target Air Compressor Platforms The contactor primarily drives the heavy-duty power stages of Atlas Copco GA series oil-injected rotary screw compressors. In particular, it serves major large-scale industrial platforms including the GA110, GA132, and GA160 compressor families. Additionally, certain oil-free air compressors and large centrifugal units rely on this exact part number to manage their main power supply. 2. Star-Delta (Y-Δ) Control Systems Within traditional star-delta starter enclosures, this heavy电气件 routinely assumes the role of either the Main Contactor or the Delta Contactor. As a result, the unit safely manages the intense current transitions that occur when the compressor switches from initial start-up torque to full-speed operational loading. 3. VSD Bypass Isolation In modern Variable Speed Drive (VSD) air compressors that feature full-pressure backup systems, this component functions as the primary line isolation contactor. Consequently, it facilitates a secure, instant transition back to standard grid frequencies if the variable frequency inverter requires maintenance. Atlas Copco 1089941558 Contactor AX185-30-11 (4) Component Identification & Unboxing Completeness To facilitate rapid on-site verification, technicians should examine the physical layout of the genuine package. In terms of physical dimensions, the thick, shock-absorbent original logistics box measures a perfect cube of 260 mm × 260 mm × 260 mm.
