Product Description

Environmental Conditions

Ambient air temperature: -15℃ to +40℃, with a daily average temperature not exceeding +35℃. Derating operation is required if conditions are exceeded.

Altitude: Suitable for installations at altitudes not exceeding 2500m.

Relative humidity: Not exceeding 50% at +40℃. Higher humidity (e.g., 90% at +20℃) is permissible at lower temperatures.

Installation tilt: Must not exceed 5 degrees; the cabinet array should remain level.

Location requirements: Installation sites should be free from severe vibration, impact, and corrosive elements.

Technical Characteristics

Flexible Structure: Modular design using 8MF type open steel profiles (20mm module) with interchangeable drawers.

Safety & Reliability: Complete isolation between functional units, busbars, and cables. Features clear mechanical interlocking for open, closed, test, and withdrawn positions.

Short-Circuit Strength: Rear-mounted horizontal busbar configuration enhances resistance to electric shock and stress.

User-Friendly Operation: Smooth push-pull drawer mechanisms and a dedicated cable compartment for easy entry and exit.

Versatile Application: Ideal for systems up to 400V (690V) with rated currents up to 4000A.
