Product Functions
◆Visible Circuit Isolation: Provides clear physical disconnection for safe maintenance and repair work on de-energized circuits.
◆No-Load Switching: Capable of making and breaking circuits under no-load conditions while withstanding rated voltage across the open contacts.
◆Manual Operation: Designed for reliable operation with the CS6-1 manual operating mechanism, ensuring positive contact movement and visual confirmation of position.
◆Voltage Withstanding: Maintains dielectric strength across open contacts to ensure complete isolation from energized systems.
◆Status Indication (Optional): Available with electrified display option for visual indication of line status.
Applicable Environment
◇Rated System: Suitable for 12kV, 50Hz three-phase AC indoor power systems.
◇Temperature Range: Reliable operation in ambient temperatures from -25℃ to +40℃.
◇Installation Altitude: Standard design for elevations below 1000 meters (high altitude variant available).
◇Humidity Tolerance: Withstands monthly average humidity ≤90% and daily average ≤9%.
◇Seismic Resistance: Capable of withstanding earthquake intensity up to 8 degrees.
◇Air Quality: Suitable for locations free from fire, explosives, corrosives, and severe vibration (pollution abatement variant available).
Product Highlights
◆Application-Specific Variants: Available in multiple configurations pollution abatement for industrial areas, high altitude for above 1000m, and electrified display for visual safety.
◆Proven Manual Operation: Features the CS6-1 manual mechanism, ensuring reliable, positive action with clear visual contact position indication.
◆Cost-Effective Isolation: Provides essential disconnecting functionality at an economical price, ideal for budget-conscious projects without compromising reliability.
◆Simple Maintenance Design: Straightforward construction allows for easy inspection and maintenance of contacts and mechanisms, reducing downtime and service costs.
◆Compact Indoor Footprint: Space-efficient design facilitates installation in crowded switchgear compartments and existing panel layouts.
◆Versatile Application Range: Ideal for various indoor setups, including distribution panels, substations, and industrial centers that require visible disconnect capability.
