The ABB AF265-30-11-13 1SFL547002R1311 is a heavy-duty industrial AC contactor engineered for reliable switching and control of high-power AC motors and electrical loads in demanding automation systems—specifically optimized for applications requiring high current handling capacity, robust arc suppression, and flexible control integration (e.g., large pumps, compressors, fans, and industrial machinery in manufacturing, utilities, and heavy industry). It functions as a "high-power electrical switch," using an electromagnetic coil to actuate power contacts, enabling safe remote control of high-current loads while withstanding frequent switching cycles and harsh operating conditions. Designed to comply with global electrical safety standards, it balances performance, durability, and safety for high-power switching needs. Below is its detailed specification:
- Product Model: ABB AF265-30-11-13 (Ordering Part Number: 1SFL547002R1311)
- Product Series: ABB AF-Series Heavy-Duty AC Contactors (High-Power Load Switching)
- Core Function: Switches high-power AC loads (e.g., large 3-phase motors); provides advanced arc suppression during contact operation; enables remote control via low-voltage coil signals; integrates with overload relays for comprehensive motor protection; supports frequent switching in heavy-duty applications
- Electrical & Switching Specifications:
- Mechanical & Environmental Specifications:
- Compliance Standards: CE, UL 508, CSA C22.2 No.14, IEC 60947-4-1, RoHS, EN 61000-6-2 (EMC immunity) |
- High-Power AC-3 Duty Rating: 265A rated current at 400V (AC-3)—specifically designed for heavy-duty motor control (up to 132kW), handling frequent starts/stops (120 starts/hour) in applications like large compressors and water pumps.
- Robust Arc Suppression: Multi-chamber ceramic arc extinguishing system—rapidly extinguishes electrical arcs during contact operation, reducing contact erosion and extending service life to 1.2 million+ operations, lowering maintenance costs.
- Integrated Auxiliary Contacts: 1NO+1NC auxiliary contacts (10A AC-15)—eliminate the need for add-on contact blocks, simplifying control logic for interlocks (e.g., emergency stop circuits) and status monitoring (e.g., "motor running" indicators).
- Global Voltage Compatibility: Coil options from 24V DC to 400V AC—suits diverse electrical systems worldwide (e.g., 400V AC in industrial plants, 24V DC in control cabinets), reducing inventory complexity for global operations.
- Heavy-Duty Construction: Flame-retardant UL 94 V0 housing with metal reinforcing—withstands mechanical stress from high current loads and vibration, ensuring reliability in rugged environments (e.g., mining, steel mills).
- Wide Temperature Range: -30℃~+70℃ operating range—functions reliably in extreme conditions, from cold storage facilities to high-temperature industrial ovens, without performance degradation.
- Seamless Protection Integration: Compatible with ABB TA/TMAX overload relays—forms a complete motor protection system (overcurrent, overload, phase loss), meeting IEC 60947-4-1 safety standards.
- Heavy Industry & Manufacturing: High-power motor control:
- Steel Mills: Controls large rolling mill motors (up to 132kW)—265A capacity handles high inrush currents; ceramic arc chambers withstand frequent switching during steel forming cycles.
- Cement Plants: Switches power to kiln drive motors and conveyor systems—wide temperature range (-30℃~+70℃) tolerates plant heat; vibration resistance prevents contact failure near grinding equipment.
- Water & Wastewater Utilities: Large pump control:
- Water Treatment Plants: Controls high-capacity booster pumps (100kW~132kW)—AC-3 duty handles daily start/stop cycles; auxiliary contacts integrate with level sensors for automatic operation.
- Sewage Pumping Stations: Switches submersible pump motors in harsh environments—flame-retardant housing reduces fire risk; 95% humidity tolerance suits damp pump houses.
- Energy & Power Generation: Turbine & generator auxiliaries:
- Power Plants: Controls boiler feedwater pumps and induced draft fans—high breaking current (1325A) handles motor inrush; compatibility with overload relays prevents damage during grid fluctuations.
- Wind Farms: Switches power to pitch control motors and transformer cooling fans—-30℃ operation ensures reliability in cold climates; robust construction withstands turbine vibrations.
- Building & Infrastructure: Large HVAC & equipment:
- Commercial Complexes: Controls large chiller compressors and air handling units—230V/400V coil options fit building electrical systems; auxiliary contacts integrate with BMS for energy management.
- Airports & Stadiums: Switches power to large escalator drives and irrigation pumps—high duty cycle (120 starts/hour) handles peak demand periods; wide voltage range tolerates grid variations.
