Product Functions
◆Load Breaking & Making: Capable of safely switching load currents and over-currents.
◆Short-Circuit Protection: Integrates a current-limiting fuse to effectively interrupt short-circuit currents, protecting downstream equipment.
◆Spring-Operated Mechanism: Employs a spring-storage mechanism ensuring that the ON/OFF speed is independent of the operator's action, guaranteeing consistent performance.
◆Three-Position Switching: Combines load switch, earthing switch, and fuse functions in a single, interlocked unit.
◆Remote Operation Ready: Supports both manual operation and AC/DC electric operation, making it easy to implement "three remote" functions.
Applicable Environment
◇Rated Voltage: Suitable for 12kV three-phase AC distribution systems.
◇Temperature Range: Reliable operation in ambient temperatures from -25℃ to +40℃.
◇Installation Altitude: Suitable for installation at elevations up to 1000 meters.
◇Humidity Tolerance: Designed to withstand daily average humidity ≤95% and monthly average ≤90%.
◇Seismic & Safety: Capable of withstanding earthquakes up to degree 8 and is certified for environments with no fire or explosion hazards.
◇Pollution Level: Rated for pollution degree level 2.
Product Highlights
◆Integrated & Compact Design: Fuses, switches, and mechanisms are housed in a single, compact framework for flexible combination, easy installation, and space-saving.
◆Superior Insulation & Safety: Static contacts feature individual insulation covers, preventing internal arc flashovers. A unique valve structure automatically isolates the fracture after opening, enhancing protection for ring main units (RMU).
◆High Electrical Durability: Features copper-tungsten arcing contacts and main contacts, ensuring reliable conductivity and an extended operational life.
◆Robust Mechanical Interlocking: Incorporates reliable mechanical interlocks between the load switch, earthing switch, and fuse to meet all "Five Anti" safety requirements, preventing maloperation.
◆Maintenance-Friendly & Reliable: Known for easy maintenance and simple operation, this series has achieved a sound reputation for its dependable performance in the field.
