Power Factor Correction Capacitors

L&T Electrical & Automation (E&A) offers a complete range of Power Factor Capacitors that are used to reduce overall power consumption and improve system efficiency. The solution also helps to maintain the required power factor thus reduces electricity bills. The design of our capacitors ensures the highest safety due to features such as self-healing technology and overpressure disconnector fuse. Different Capacitor technologies such as Metallised Poly Propylene (MPP) and Aluminium Poly Propylene (APP) films are available. MPP Capacitors are manufactured in different ranges – Standard Duty, Heavy Duty and Super Heavy Duty. APP Capacitors are available in the box configuration in the ranges of APP and Ultra Heavy Duty Capacitors. APP Capacitors are also provided with internal fuse elements for protection.

Standard Duty Box Capacitor with MCB & LED (LTBCM):

Our range of Standard duty capacitors inbuilt with MCB and LED are designed with metalized polypropylene technology and are available from 5 - 25 kVAr in Box configuration. Having all standard features, these capacitors are specially designed for industries where fixed compensation using Box type capacitors is preferred. Instead of procuring capacitor, protection device and enclosure separately, these capacitors provide a complete 3 - in - 1 solution.

• Correction of PF using Standard duty capacitor.
• Protection and isolation by integrated MCB.
• LED in each capacitor phase giving a visual indication of health status of capacitor.

3-in-1 Capacitors are the smart solution for Transformer Compensation (Cap kVAr = 1.2% of Transformer kVA Rating) and Fixed Compensation (Cap kVAr = 45% of Motor HP Rating).
