Circutor R2H541 CLZ-FPT-44/1,25-HD Three-Phase Tubular Power Capacitor

The Circutor CLZ-FPT-44/1,25-HD (code R2H541) is a three-phase tubular power capacitor from the CLZ Heavy Duty range, rated 1 kvar at 400 V and 1.25 kvar at 440 V at 50 Hz. Designed for reactive power compensation in installations with extreme operating conditions, it uses a dry-type aluminum tubular body with nitrogen gas cooling - an inert, non-flammable thermal management system. Faston terminal connections and compact 63.5 x 111 x 63.5 mm dimensions make it well suited for direct mounting inside capacitor bank assemblies.

Features and benefits:

• 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 high inrush events associated with frequent capacitor switching in automatic compensation banks.
• Compact aluminum body (63.5 x 111 x 63.5 mm, 0.36 kg) with M12 fastening screws allows flexible vertical or horizontal mounting with minimal panel space.

Applications:

• Reactive power compensation in industrial and commercial low-voltage power distribution networks.
• Fixed-stage and automatic capacitor banks serving static or variable loads.
• 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 400 V or 440 V, 50 Hz.
