## Description

The Cornell Dubilier PSU16135A is a non-polarized aluminum electrolytic capacitor specifically engineered for AC motor start applications. Housed in a rugged, compact bakelite case, this component is designed to provide the high capacitance required for motor starting torque in single-phase AC induction motors. It features dual quick-connect terminals for simplified installation and is rated for operation within a temperature range of -40 °C to 65 °C. The device complies with EIA RS-463 Type 2 standards for normal performance and is listed under UL file no. E128034, ensuring suitability for demanding industrial motor control environments.

This capacitor supports a voltage rating of 220/250 Vac and offers a capacitance range centered on the 161-193 µF specification. To enhance system reliability and extend the service life of relay contact switches, the PSU series supports optional integrated bleeder resistors. Mechanical integration is facilitated by optional mounting systems, including brackets and end caps (PL or PLA configurations) for either on-motor or off-motor mounting. With an operating frequency range of 50 Hz to 60 Hz and a robust construction, the PSU16135A provides a stable solution for intermittent-duty motor starting circuits requiring high-reliability passive components.

## **Optional Enhancements** 

End Caps Mounting Bracket 

**The Type PSU is a compact non-polar, dual voltage rated, AC  motor  start capacitor constructed in a round rugged bakelite case.  To extend the life of relay contact switches, the PSU can be purchased with optional bleeder resistors assembled with   1/4” quick-connect terminals. An optional mounting system consisting of a bracket that is attached to the capacitor case with one end cap is available. The PL end caps are for use with wiring through the bracket to the motor and the PLA end caps are for off motor mounting. Highlights**
