ARCO BMC Series Capacitor

DESCRIPTION

General

• The BMC Series capacitor design incorporates high quality three phase cells which are vacuum-impregnated metallized polypropylene filled and compact size. This series of power factor correction capacitors is suitable for low voltage linear applications

Construction

• The three phase cells which are used in the construction of the power factor banks are drawn steel rectangular cans which are vacuum-impregnated with a dielectric fluid to give added insulation, excellent corona protection, and a moisture barrier.  The capacitor cells are housed in a NEMA 3R enclosure panel.  The enclosure panel is manufactured from 16 gauge steel and is furnished with mounting holes for quick and easy installation.  Other NEMA rated enclosures are available – consult the factory

Capacitor Cell Design

• The dielectric fluid used in the capacitor cells is a green Non-PCB, non-toxic, biodegradable, and Class III combustible fluid.
• Self-healing technology in case of overload, the self-healing properties of the low loss metallized polypropylene will prevent permanent dielectric breakdown.
• Internal Pressure-Sensitive Interrupter which safely removes the capacitor from service at the end-of-life or under heavy fault conditions while still maintaining the integrity of the steel casing.   
• External resistors discharge voltage is less than 50 volts in less than 1 minute after the cell has electrically been removed from circuit.
• Standards – UL810, C22.2 No. 190 Canadian Standards, IEC 831, UL Recognized CYTW2, cUL Recognized CYTW8

Capacitor Losses

• The capacitor design has a total loss which is less than .5 Watts per kVAR at 60 HZ 25 degrees C.

Electrical Characteristics

• 240 VAC, 480 VAC, 600 VAC rated Voltage at 60 HZ
• The three phase capacitor internal connection is Delta. 
• 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 Insulation

• 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.

WARRANTY

• 5-YEAR WARRANTY on the capacitor cells
