Key Specifications
Parameter Category Specification
Product Type Motor Start Capacitor (Electrolytic or AC Film type, typically non-polarized for AC operation)
ABB Order Code / Part Number 1SFA897109R7000
Capacitance 70 µF (Microfarads) - This is the most common value indicated by the "70" in the suffix "R7000".
Rated Voltage ~250 V AC / 370 V DC (or similar, e.g., 300/330 V AC). Crucial: Must match or exceed the motor's operating voltage.
Frequency 50/60 Hz
Tolerance Typically ±5% or ±10%
Operating Temperature Range Typically -25°C to +70°C (common for motor start capacitors)
Duty Cycle Intermittent Duty (Start Duty). Designed for short-duration energization during motor start-up (a few seconds), not for continuous run operation.
Case Type Typically a cylindrical metal or plastic can with insulated terminals.
Terminal Type Usually spade terminals (6.3 x 0.8 mm quick-connect) or screw terminals.
Key Function Provides the necessary phase shift in the auxiliary winding circuit to create a starting torque for single-phase induction motors.
The ABB 1SFA897109R7000 is a motor start capacitor designed for single-phase AC motors, specifically for use in capacitor-start or capacitor-start/capacitor-run motor configurations. This type of component is critical for providing the initial phase shift and torque boost needed to start single-phase induction motors, which lack the rotating magnetic field of three-phase motors.
