Circutor R2H67N CLZ-FP-52/30-60Hz-HD Three-Phase Tubular Power Capacitor

The Circutor CLZ-FP-52/30-60Hz-HD (code R2H67N) is a three-phase tubular power capacitor from the CLZ Heavy Duty range, rated 25 kvar at 480 V and 30 kvar at 525 V on 60 Hz supplies. Designed for reactive power compensation in installations with extreme operating conditions, it uses a dry-type aluminium tubular body with nitrogen gas cooling - an inert, non-flammable thermal management system. Terminal block connections and M12 fastening make it well suited for direct mounting inside capacitor bank assemblies operating up to 525 V.

Features and benefits:

• Rated specifically for 60 Hz networks, delivering 25 kvar at 480 V and 30 kvar at 525 V so a single unit covers both common 60 Hz compensation voltages.
• Temperature Class D rating (maximum 65 °C, minimum -50 °C) allows continuous use in high-ambient switchgear cubicles and harsh industrial environments where standard capacitors would fail prematurely.
• Nitrogen gas cooling technology provides inert, non-flammable thermal management without liquid dielectrics, reducing fire risk in enclosed panel installations.
• Low dielectric losses below 0.2 W/kvar and total losses below 0.4 W/kvar limit heat generation inside the capacitor bank, supporting longer service life.
• Maximum transient current rating of 400 x In handles the high inrush events associated with frequent capacitor switching in automatic compensation banks.
• Dielectric regeneration and expansion system provide self-healing of the dielectric and overpressure protection at end of life.

Applications:

• Reactive power compensation in 60 Hz industrial and commercial low-voltage distribution networks.
• Fixed-stage and automatic capacitor banks serving static or variable loads at 480 V or 525 V.
• Power factor correction in environments with elevated ambient temperatures, high humidity, or frequent switching cycles.
• Replacement or capacity expansion of existing CLZ-HD bank stages operating at 480 V or 525 V, 60 Hz.
