Features and benefits:

• Nitrogen gas cooling is inert and non-flammable, making the capacitor safe for use in enclosed switchgear cabinets.
• Heavy Duty construction tolerates extreme ambient conditions, with a working range from -50 °C to +65 °C (class D).
• Total losses below 0.4 W/kvar keep internal heat generation low, extending the operational lifespan of the unit.
• Dry-type construction removes any risk of fluid leaks or contamination within the installation panel.
• Dielectric regeneration and expansion system provide built-in protection mechanisms for long-term capacitor reliability.

Applications:

• Static capacitor banks for power factor correction on 400 V and 440 V three-phase distribution networks.
• Automatic reactive power compensation systems connected to variable industrial loads.
• Harsh industrial environments - foundries, processing plants, outdoor substations - where elevated temperatures and high humidity demand Heavy Duty rated components.
• Panel-mounted compensation assemblies requiring a compact footprint with flexible vertical or horizontal mounting.
