Features and benefits:

• Nitrogen gas cooling system is inert and non-flammable, providing safe thermal management inside enclosed capacitor cabinets
• Heavy Duty Class D temperature rating (-50 °C to +65 °C) makes this unit suitable for extreme climates and high-heat industrial environments
• Dual voltage rating at 400 V and 440 V allows a single capacitor to serve both common European three-phase supply levels without substitution
• Integrated dielectric regeneration and expansion protection system extends service life under continuous or cyclic compensation duty
• Compact aluminum tubular body (63.5 x 188 x 63.5 mm) with M12 fastening accepts both vertical and horizontal mounting to suit standard capacitor bank frames

Applications:

• Reactive power compensation stages in automatic power factor correction (APFC) panels on 400 V or 440 V three-phase networks
• Power factor improvement in industrial installations operating with static or variable loads
• Replacement or expansion unit in existing CLZ-HD series capacitor banks
• Compensation duty in enclosed cabinets or installations subject to extreme temperatures, high humidity, or other harsh operating conditions
