Circutor R2H543 CLZ-FPT-44/3-HD Three-Phase Tubular Power Capacitor

The Circutor CLZ-FPT-44/3-HD (code R2H543) is a three-phase tubular power capacitor from the Heavy Duty range, rated at 2.5 kvar at 400 V and 3 kvar at 440 V at 50 Hz. Built with a dry-type aluminum tubular casing and Faston (type F) terminals, this unit is designed for reactive power compensation in capacitor banks where harsh operating conditions require extended-life, high-temperature-resistant components.

Features and benefits:

• Nitrogen gas refrigeration provides inert, non-flammable internal cooling, improving safety in enclosed panel assemblies
• Dielectric regeneration and built-in expansion system extend service life under demanding load cycles
• Temperature class D rating covers a working range from -50 °C to a maximum of 65 °C, suitable for extreme site environments
• Total losses below 0.4 W/kvar limit internal heat generation and reduce energy dissipation within the capacitor bank
• Aluminum tubular casing accommodates both natural-convection and forced-air cooling, offering flexibility in cabinet layout

Applications:

• Reactive power compensation in static or variable-load capacitor banks on 400 V and 440 V three-phase networks
• Power factor correction in industrial distribution cabinets and switchgear panels exposed to harsh environmental conditions
• Installations requiring high temperature resistance and long operational life between maintenance intervals
• Compact capacitor bank assemblies calling for tubular units with Faston terminal connections
