Solar Type 9133-1 Three Phase Capacitor Assembly for Line-to-Line Capacitance in Delta Connected Power Systems
This handy device contains three capacitors, 10 µF each, connected to provide capacitance from phase A to B, A to C, and B to C. The capacitors are rated at 270 VAC. As a safety feature, each capacitor is paralleled with a 500 K resistor to prevent a voltage charge from remaining on the assembly after power is disconnected. It is fitted with 1/4-28 feedthru studs to facilitate making connection from three phase power to a three phase load up to 100 A. The Type 6512-106R capacitor can be used for the neutral in 'wye' connected power systems.

Capacitance: 3 x 10 µF ± 10% @ 25° C
Voltage rating: 270 VAC at 60 Hz, 135 VAC at 400 Hz
Current rating: 100 A (limited by 1/4-28 threaded terminals)
Temperature: -55° C to 100° C (125° C with 50% voltage derating)
Dissipation factor: <1% @ 25° C
Dielectric strength: Twice rated voltage @ 25° C
Insulation resistance: At rated voltage or less for a period of two minutes, the insulation resistance will exceed 2500 MΩ @ 25° C line to line. However, insulation resistance in excess of 500 kΩ cannot be measured due to the bleeder resistors built into the units.
Bleeder resistor: Line to line internal bleeder resistors of 500 kΩ included
Life test: Life test: Will withstand the application of 600 VDC @ 85° C for 250 hours
Terminals: 1/4-28 threaded feed-thru studs
Dimensions: Dimensions: 4.00" wide x 4.00" high x 4.50" deep (10.16 cm x 10.16 cm x 11.43 cm)
