Circutor R2H54N CLZ-FP-44/30-HD Three-Phase Tubular Power Capacitor

The Circutor CLZ-FP-44/30-HD (code R2H54N) is a three-phase tubular power capacitor from the Heavy Duty range, rated at 25 kvar at 400 V and 30 kvar at 440 V for reactive power compensation. Enclosed in an aluminum tubular casing with terminal block connections, it employs nitrogen gas refrigeration technology and is engineered to sustain performance under extreme operating conditions. This 50 Hz unit conforms to IEC 60831-1-1/2 and VDE 560 4000 and is intended for static and variable load compensation in industrial capacitor banks.

Features and benefits:

• Nitrogen gas cooling - inert and non-flammable - delivers effective thermal management beyond what air-cooled designs offer, supporting longer service life in high-stress environments
• Total losses below 0.4 W/kvar reduce continuous heat generation, limiting thermal stress on surrounding components in the panel
• Residual voltage discharges to below 50 V within 1 minute of disconnection, helping meet safety requirements before maintenance access
• Temperature class D rating allows operation from -50 °C to 65 °C, making the unit viable for outdoor enclosures and industrial sites with wide thermal swings
• Built-in dielectric regeneration and expansion protection extend operational life without requiring additional external protection devices

Applications:

• Reactive power compensation in industrial capacitor banks serving static loads
• Power factor correction in installations with variable or fluctuating load profiles
• Compensation stages in environments with elevated temperatures, high humidity, or mechanical vibration where standard capacitors are unsuitable
• Three-phase low-voltage distribution networks operating at 400 V or 440 V, 50 Hz
