On Sale SCHNEIDER ELECTRIC  SQUARE D LF3 17.5KV 3150AMP CITCUIT BREAKER Good Condition and come with 3 months warranty,  a premium three-pole, indoor medium-voltage switchgear engineered for public, industrial, and heavy infrastructure power networks. Operating primarily on advanced SF6 gas self-expansion breaking technology, this specific high-amperage model isolates high-capacity electrical faults while maintaining an incredibly compact footprint.

Specifications

• Rated Voltage: Up to 17.5 kV at 50/60 Hz.

• Continuous Rated Current: 3150 A.

• Interruption Medium: SF6 gas contained within a sealed-for-life pressure system.

• Operating Mechanism: Motorized, spring-charged RI stored-energy mechanical system that allows fast, operator-independent open/close cycles.

• Short-Circuit Performance: Rated to handle short-circuit breaking currents up to 50 kA depending on the exact configuration

Operational & Safety Highlights

• Low-Pressure Safety: Operates at a low relative gas pressure of just 0.15 MPa (1.5 bars), heavily minimizing structural seal stress. 

• Low Maintenance: Built for an industrial lifespan of 30 years, requiring simple servicing only on the front-facing operating mechanism once every 10 years or 10,000 operations. 

• Harsh Environment Resilience: Includes specific anti-seismic qualified variants making it heavily sought after for heavy petrochemical applications, thermal power plants, and nuclear installations. 

• Retrofit & Modernization: Frequently deployed under the Schneider Electric EcoFit program  to safely upgrade aging existing substations without requiring full switchboard replacement.
