Circutor R2H542 CLZ-FPT-44/2.5-HD Three-Phase Tubular Power Capacitor

The Circutor CLZ-FPT-44/2.5-HD (code R2H542) is a three-phase dry-type tubular power capacitor from Circutor's Heavy Duty CLZ-HD range, rated at 2 kvar at 400 V and 2.5 kvar at 440 V on 50 Hz three-phase networks. Housed in an aluminum tubular casing with nitrogen gas thermal management, it is engineered for power factor correction in installations subject to harsh or extreme environmental conditions.

Features and benefits:

• Nitrogen gas cooling is inert and non-flammable, providing a safe thermal management solution across demanding duty cycles
• Temperature class D permits operation from -50 °C to a peak of 65 °C, covering a broad range of industrial environments
• Dielectric losses held below 0.2 W/kvar limit self-heating and contribute to higher compensation efficiency
• Built-in dielectric regeneration and expansion protection extend service life under sustained or overloaded operating conditions
• Compact aluminum tubular form factor of 63.5 x 140 x 63.5 mm and 0.53 kg weight supports both vertical and horizontal cabinet mounting

Applications:

• Reactive power compensation in fixed or switched capacitor bank assemblies at 400 V or 440 V, 50 Hz
• Power factor correction in industrial facilities with static or variable load profiles
• Capacitor bank installations in high-temperature or rough environments where standard-duty units are unsuitable
• Upgrade or replacement of existing capacitors in panels requiring extended operational life under extreme conditions
