Circutor R2H54G CLZ-FP-44/18.2-HD Three-Phase Tubular Power Capacitor

The Circutor CLZ-FP-44/18.2-HD (code R2H54G) is a three-phase tubular power capacitor from the Heavy Duty range, rated at 15 kvar at 400 V and 18.2 kvar at 440 V for 50 Hz systems. It is engineered for reactive power compensation in installations exposed to extreme operating conditions, with a dry-type aluminum casing and an integrated nitrogen gas cooling system.

Features and benefits:

• Nitrogen gas cooling - an inert and non-flammable refrigerating system - allows operation in environments where conventional cooling methods are unsuitable
• Heavy Duty aluminum tubular casing sustains maximum ambient temperatures up to 65 °C, extending service life in high-heat installations
• Dual voltage rating (400 V and 440 V) means a single unit covers both common European supply voltages without needing a separate variant
• Built-in dielectric regeneration and expansion protection help maintain performance over time in rough operating environments
• Operating range down to -50 °C makes the unit suitable for outdoor enclosures, cold storage, or unheated industrial spaces

Applications:

• Reactive power compensation in fixed or automatic capacitor banks at 400 V or 440 V / 50 Hz
• Power factor correction in industrial and commercial facilities with static or variable electrical loads
• Switchgear and distribution panels installed in locations with extreme heat, cold, humidity, or dust
• Replacement or extension of capacitor banks in demanding process and manufacturing environments
