0.5HP (0.37kW) Control Box

Key Components Inside

• Starting/Running Capacitor: This is the most critical part. For a 0.5HP motor, it usually houses a capacitor (typically in the range of 20$\mu$F to 30$\mu$F). It provides the phase shift needed to give the motor torque to start spinning.

• Thermal Overload Protector (Circuit Breaker): A reset button (usually 5A or 8A for 0.5HP) that pops out if the pump jams or overheats. This prevents the motor windings from burning out.

• On/Off Switch: Usually a waterproof rocker switch with an internal light.
