Circutor R2H54B CLZ-FP-44/10-HD Three-Phase Tubular Power Capacitor

The Circutor CLZ-FP-44/10-HD (code R2H54B) is a three-phase tubular power capacitor from the Heavy Duty range, built for reactive power compensation in 400 V and 440 V three-phase systems at 50 Hz. It provides 8 kvar at 400 V and 10 kvar at 440 V, and its dry-type aluminum construction is engineered to perform in installations with extreme working conditions including high temperatures and humidity.

Features and benefits:

• Nitrogen gas cooling technology provides an inert, non-flammable refrigeration system that delivers high-performance thermal management inside the tubular enclosure.
• Temperature class D rating allows operation up to a maximum of 65 °C, making the unit suitable for demanding industrial environments where heat build-up is a concern.
• Total losses below 0.4 W/kvar minimise self-heating during continuous operation, reducing stress on the capacitor and surrounding equipment.
• Integrated dielectric regeneration and expansion system protection extend service life in installations subject to voltage surges and transients.
• Supports both vertical and horizontal mounting with M12 fastening screws, giving flexibility when fitting into existing capacitor bank enclosures.

Applications:

• Fixed reactive power compensation in industrial capacitor banks connected to 400 V or 440 V three-phase distribution networks.
• Power factor correction in installations with variable loads, used as part of automatic switching capacitor banks.
• Environments with extreme operating conditions such as high ambient temperatures, humidity up to 95 %, or installation altitudes up to 4000 m.
• Replacement or expansion of Heavy Duty capacitor stages in existing reactive energy management systems at 50 Hz.
