DESIGN / CONSTRUCTION: AMBER series ‘PI’ Low Voltage Three Phase Power Capacitors in ‘Impregnated & Protected’ design are manufactured out of Modules made of Low Loss Self-Healing Metallised Polypropylene Film, impregnated in non-PCB oil of low viscosity. The Modules incorporate internal pressure disconnection system which fully protects the Modules against bursting in case of fault. The modular construction allows repair / maintenance of the assembly at the component level.
DISCHARGE RESISTORS: Fitted to reduce the voltage to a level below 75V within 3 minutes of switch-off.
TERMINATION: Plated Terminals for termination of Cables.
HOUSING: Electrostatic Powder Coated MS sheet, 1 mm, with ample ventilation louvers.
IEC 60831 (2014-02) Parts 1 & 2 “Shunt Power Capacitors of the self-healing type for AC Systems having a rated voltage up to and including 1000 V”
-25°C / D (Minimum ambient air temperature: -25°C Maximum ambient air temperature during a year: +55°C Highest mean over any period of 24 hours: +45°C Highest mean over any period of 1 year: +35°C)
Indoor, the capacitors are specially suited for environments having consistently high ambient temperatures and high harmonic levels.
Less than 0.5 W / kVAr
CONTINUOUS OVER VOLTAGE
1.1 Un (except transients)
CONTINUOUS OVER CURRENT
1.3 In (except transients)
Between terminals: 2.15 Un AC for 2 seconds Terminals to case: 3 kV AC for 10 seconds
– 5% / +10%
12.5 kVAr, 25.0 kVAr & 50 kVAr, for ranges not mentioned here, please enquire.
WARNING: Capacitor replacement may be hazardous since residual voltage may be present across the capacitor terminals. Always discharge capacitors by short-circuiting the terminals with an insulated wire, even though discharge resistors may have been provided.
ATTENTION: Capacitors covered by this catalogue comply with international standards such as IEC, VDE, BS, EN, UL etc. It is the user’s responsibility to take utmost care both in the selection of capacitors for a particular usage, and their correct installation. AMBER shall not be liable for any consequential damages occurring for any reasons what-so-ever.
Due to continuous research and development in our technology, the data and sizes given in this catalogue may be changed without prior notice.
Please reconfirm the dimensions with AMBER if this information is crucial for your application.
