Description
The RS9000A02 is a centrifugal rotating switch manufactured by Baldor (now part of ABB), designed for use with 210-frame electric motors. It plays a critical role in motor start-up by engaging and disengaging the start winding based on motor speed. With a torque rating of 300-4-60, it features a 1.375-inch bore and a 3.625-inch outer diameter. The switch activates (cut-in) between 600–1000 RPM and deactivates (cut-out) between 1300–1450 RPM under load.
Features
- Centrifugal Activation: Automatically engages and disengages motor start windings based on rotational speed—cut-in between 600–1000 RPM and cut-out between 1300–1450 RPM under load.
- Motor Compatibility: Specifically designed for 210-frame electric motors, commonly used in HVAC and industrial applications.
- Precision Fit: Features a 1.375-inch bore and 3.625-inch outer diameter, ensuring accurate alignment and reliable operation.
- Torque Rating: Rated at 300-4-60, suitable for 4-pole motors operating at 60 Hz.
- Durable Construction: Built to withstand demanding environments with a compact, lightweight design (approx. 0.425 lbs).
- Reliable Performance: Ensures smooth motor startup and protects windings from prolonged engagement, extending motor life.
