ABB 1SDA073760R1 Contactor
Product Description
Industrial AC contactor for power circuit switching, designed to control medium-power AC motors and electrical loads—core for motor starting, stopping, and overload protection in industrial automation (e.g., manufacturing, power auxiliaries).
Key Specs
  • Rated Current: 95A (AC-3 duty, 400V AC); max switching current 10x rated (950A).
  • Voltage Rating: 400V AC (main circuit); control voltage options: 24V DC/110V AC/230V AC.
  • Contact Configuration: 3 poles (main contacts, NO); 1 auxiliary contact (NO/NC configurable).
  • Mechanical Life: ≥10 million operations; electrical life (AC-3): ≥1 million operations.
  • Env: -25°C~+60°C, 5%-95% RH (non-condensing), IP20 (installation in control cabinets).
  • Protection: Compatible with ABB thermal overload relays (e.g., TA25DU) for overload protection.
Core Advantages
  1. High switching capacity: 95A rated current handles medium-power motors (e.g., 45kW, 400V AC).
  1. Durable design: Long mechanical/electrical life reduces replacement frequency in heavy-duty use.
  1. Flexible control voltage: Multiple options (24V DC/110V AC/230V AC) fit diverse system power supplies.
  1. Easy integration: Standard mounting footprint (DIN rail/bolt-on) compatible with industrial control panels.
Applications
  • Controls 45kW AC motors in manufacturing conveyor systems (start/stop, emergency cut-off).
  • Switches power for water treatment pump motors (400V AC, 90A max load).
  • Manages HVAC fan motors in large industrial buildings (reliable on/off switching).
Precautions
  1. Wiring: Main circuit use 16mm² copper cables; control circuit use 1.5mm² cables; torque terminals to 2.5-3N·m.
  1. Load matching: AC-3 duty for motor control—do not use for resistive loads (AC-1) beyond 120% rated current.
  1. Protection matching: Pair with thermal overload relay (e.g., TA25DU-95) to prevent motor overload.
  1. Installation: Keep 5cm clearance from heat sources; avoid direct vibration (use anti-vibration mounts if needed).
  1. Maintenance: Check contact wear annually (replace if contact erosion >1mm); clean dust from coil area quarterly.
