Power factor correction capacitors store and redistribute reactive power. When a capacitor assembly is connected to an electrical system containing an inductive load, e.g., motor, the load will require less reactive power from the utility.

Low power factor caused by inductive loads results in increased line losses and possible surcharges or penalties billed by electric utility providers.

Myron Zucker, Inc. offers a wide range of power factor correction capacitors for various applications to ensure optimal power utilization.

Our products are specified in kilovolt-amperes reactive (kVAR) for three-phase voltages of 240, 480, and 600 VAC. Our capacitor assemblies are also designed for other voltage or phase applications.

Myron Zucker, Inc. offers both fixed and automatic products. Fixed capacitor assemblies are applied to constant load conditions either at the load, branch panel, or service entrance. Automatic capacitor assemblies correct power factor under varying load conditions, typically at the service entrance for facility-wide correction.

Please view our Power Factor Correction Application Guide for detailed information.

POWER FACTOR CORRECTION CAPACITORS - FIXED
Fixed capacitor systems are ideally suited for power factor correction in applications where the load does not change or where the capacitor is switched with load, such as the load side of a motor starter.

Myron Zucker, Inc. offers several options to meet your application needs.

• Calmount^® series: Ideally suited for individual motor loads and small or medium substations
• Traymount^® series: Specifically designed for motor control centers (MCC)
• Capacibank^® series: Applied to individual motors, large substations, or service entrance applications

POWER FACTOR CORRECTION CAPACITORS - AUTOMATIC
Automatic capacitor banks are the appropriate choice for power factor correction in applications where the electrical load is not constant and requires varying amounts of reactive power. An automatic capacitor bank measures power factor and switches capacitors in and out of service to maintain target power factor.

• Autocapacibank™ series: Located strategically located throughout an electrical distribution system or the service entrance when the electrical system has less than 15% non-linear loads
• ZT Capacibank series: Designed to improve poor power factor under rapidly changing load conditions. The ZT series utilizes thyristor soft-switching technology which prevents transients.
