                                  • Rated Thermal Current: Approx. 960 A continuous

                                  • DC Make/Break Capability: Typical rated for heavy duty DC applications, e.g., up to 600 V DC making capacity and 300 V DC breaking capacity

                                  • Poles / Contact Configuration: Generally 3‑pole (2 N.O. + 1 N.C.); 2‑pole versions available

                                  • Standard Auxiliary Contacts: 1 N.O. + 1 N.C.; expandable up to 4 N.O. + 4 N.C.

                                  • Coil Voltage: Standard coil is 120 V AC (“‑1L” suffix); other voltages selectable according to coil‑voltage chart

                                  • Construction Features: Double‑break main contacts with magnetic arc chutes for enhanced arc extinguishing performance

                                  • Mounting / Terminals: Screw‑terminal, panel mount suitable for high‑power control cabinets

                                  • Application Context: Designed for DC adjustable speed drives and high‑power switching applications

                                  Advantages & Features

                                  • Very High Capacity: 960 A class allows handling very high loads and large industrial motor control needs

                                  • Optimized for Drive Systems: Specifically designed for DC/adjustable speed drives, offering high make/break capability

                                  • Superior Arc‑Extinguishing: The double‑break contact and magnetic arc chute design reduce wear and extend service life

                                  • Expandable Auxiliary Contacts: Standard monitoring contacts, with flexibility to expand for system integration

                                  • Brand & System Integration: As part of ABB’s established drive contactor series, offers strong compatibility and spare parts support

                                  • Industrial Environment Ready: Built for heavy duty, high power industrial applications

                                  Application Areas

                                  • Large adjustable‑speed drive systems: DC drives, AC variable frequency drives, high inertia load equipment

                                  • High‑power motor control panels: Mining, steel, chemical, large pump systems, heavy haul conveyors

                                  • Automation with heavy loads: Large conveyors, heavy machinery switching, dynamic braking systems

                                  • System upgrades and spare replacements: For installations requiring high capacity contactors or upgrading older drive systems

                                  Precautions

                                   

                                  • Verify complete model code, coil voltage, pole count and auxiliary contact configuration for compatibility

                                  • Ensure power is disconnected before installation and implement ESD and grounding precautions

                                  • Because this is high‑power equipment, ensure terminal wiring, conductor size and ventilation meet specification

                                  • For DC switching or regenerative systems, confirm that make/break capability matches system voltage and current

                                  • Environmental conditions strongly affect lifespan: ensure proper temperature, humidity, dust, corrosion, and vibration control

                                  • When using second‑hand or refurbished equipment, check contact wear, coil condition, runtime hours and maintenance history

                                  • When planning future system upgrades, evaluate whether this model still suits or whether a newer contactor series should be used
