Circutor R2H848 CLZ-FPT-44/7.5-HD Three-Phase Tubular Power Capacitor

The Circutor CLZ-FPT-44/7.5-HD (code R2H848) is a three-phase tubular power capacitor from the Heavy Duty CLZ-HD range, intended for reactive energy compensation in capacitor banks operating at 400 V or 440 V. It delivers 6.25 kvar at 400 V and 7.5 kvar at 440 V at 50 Hz, with a dry-type aluminum tubular enclosure that uses nitrogen gas refrigeration to sustain performance under extreme working conditions. The design supports temperatures from -50 to +65 °C and humidity up to 95%, making it suitable where standard capacitors cannot be used.

Features and benefits:

• Nitrogen gas refrigeration - an inert and non-flammable cooling medium - provides effective thermal management within the sealed aluminum enclosure throughout continuous operation in demanding conditions.
• Temperature class D rating with a working range of -50 to +65 °C allows installation in harsh environments such as outdoor enclosures, cold-storage facilities, or high-temperature industrial premises where standard capacitors are not rated.
• Total losses under 0.4 W/kvar limit self-heating within the capacitor bank cabinet, reducing thermal stress on adjacent components and supporting longer service intervals.
• Compact Faston terminal construction measuring 63.5 x 215 x 63.5 mm fits into standard capacitor bank cabinets, with vertical or horizontal mounting options and M12 earth conductor fastening for straightforward installation.
• Dual voltage rating at 400 V and 440 V allows one product to cover both common European three-phase network voltages without requiring separate capacitor variants.

Applications:

• Static capacitor banks for reactive power compensation in three-phase industrial low-voltage distribution systems at 400 V or 440 V.
• Automatic (variable) capacitor banks connected to installations with static or variable electrical loads requiring dynamic power factor correction.
• Power factor correction in industrial, outdoor, or process environments with extreme temperatures, high relative humidity, or other severe ambient conditions.
• Reactive energy management in three-phase networks where a compact, tubular, dry-type capacitor unit with high temperature resistance is specified.
