Capacitor Start 125-156UF is engineered to provide the essential starting torque required by single-phase induction motors. With a capacitance range of 125–156 microfarads (µF) and a voltage rating typically between 110V and 350V AC, this electrolytic start capacitor is activated for a few seconds during motor start-up and is automatically removed from the circuit by a relay or centrifugal switch after the motor reaches running speed. The capacitor’s robust cylindrical design, often housed in durable plastic or bakelite, incorporates standard connection terminals (such as 6.3mm double spade or Faston terminals) and may include a mounting stud or bracket for secure installation.

Key Features Capacitor Start 125-156UF:

• Capacitance: 125–156 µF for strong motor starting power
• Voltage rating: available in 110V, 125V, 250V, 320V, and up to 350V AC (confirm with product label)
• Tolerance: typically ±10% to ±15%
• Electrolytic, non-polarized construction for intermittent use
• Compatible with 50/60 Hz AC motors
• Cylindrical design (commonly ~36–46mm diameter, ~70–86mm height)
• Standard spade or Faston terminals for easy wiring
• Operating temperature: often -10°C to +65/75°C
• Intended for applications such as pumps, compressors, pressure washers, and HVAC units
• Must only be used as a start capacitor (intermittent duty, not continuous)

Capacitor Start 125-156UF is a crucial component for ensuring motors overcome initial inertia, especially in demanding or high-load environments. Always confirm compatibility by matching the capacitance and voltage ratings with your specific motor requirements before installation.
