Features and benefits:

• Nitrogen gas cooling system is inert and non-flammable, enabling reliable continuous operation up to a maximum of 65 °C.
• Dry-type construction in an aluminum tubular casing removes any liquid dielectric, eliminating leak risk and reducing routine maintenance.
• Operating temperature down to -50 °C means the unit can be installed in cold-climate or outdoor-adjacent environments without performance loss.
• Supports both natural and forced-air ventilation, giving flexibility when integrating into different panel or cabinet configurations.
• Vertical or horizontal mounting with M12 fastening and earth conductor simplifies installation in standard switchgear enclosures.

Applications:

• Reactive power compensation in static or variable-load capacitor banks on three-phase 400 V / 440 V industrial networks at 50 Hz.
• Power factor correction in installations with extreme working conditions such as elevated ambient temperatures or high humidity.
• Integration into automatic power factor correction systems requiring heavy-duty capacitors with extended service life.
• Industrial panels and switchgear where compact physical dimensions (85 x 276 x 85 mm) and robust thermal performance are both required.
