Standard Duty Power Factor Correction Capacitor

Construction

The fixed capacitor banks are designed for low voltage linear applications and incorporate high quality single phase cells which are wired in a three phase Delta configuration. The capacitors are housed in a NEMA 3R enclosure panel. The enclosure is manufactured from 16 gauge steel and is furnished with mounting holes for quick and easy installation. Other NEMA rated are available – consult the factory

Capacitor Design

• Internal Pressure Interrupter meets UL 810 requirements. Discharge voltage is less than 50 volts in less than 1 minute after the cell has electrically been removed from circuit
• Environmentally safe epoxidized soybean-oil dielectric fluid. Soybean-oil is environmentally compatible and biodegradable

Capacitor Losses

The capacitor design has a total loss which is as low as 2 Watts per kVAR.

Electrical Characteristics

• Capacitance Tolerance is + or – 15%.
• Overcurrent Tolerance is 135% of rated current continuously.
• Overvoltage Tolerance is 110% of rated voltage
• Standard Operating Temperature is -40 F to +115 F. Operation above 115 F will shorten the capacitor life

Wiring Cable Installation

All internal conductors are insulated stranded copper wire rated at 90 C.

Fuse Protection & Indicator Lights (Optional - Add Suffix Letter "L" to Catalog Number)

The internal protection fuses are time-delay and rated at 600 VAC with the sizing based upon the nominal amperage rating of the kVAR size in accordance with the National Electric Code requirements.

• For single phase applications change Prefix Number from 3 to 1
• For 208 VAC applications divide kVAR size by .75 to find equivalent in 240 VAC size
