Siemens VS17005R Vacuum Interrupter 12/36 KV 2500A Sealed Withdrawable

1. Product Highlights
• Rated Parameters: 12 kV system voltage, 2500 A rated current, 31.5 kA rated short-circuit breaking current, and a mechanical life of up to 30,000 cycles.
• Dual-Ceramic Shielded Structure: The static and moving contact cups, combined with the main shield, effectively reduce the post-arc reignition rate and enhance insulation strength.
• Low Cutoff Current and Low Leakage: Siemens CuCr contact material combined with high vacuum provides low cutoff current and low leakage, extending service life.
• Full-Capacity Verification: 50 full-capacity breaking cycles were completed on a ZN-65 test circuit breaker, with a DC component of up to 78%, demonstrating stable performance.
• Excellent Temperature Rise Performance: The temperature rise at 2500 A continuous operation is only 63°C, well below the 75°C limit, ensuring system safety.
• Plug-and-Play: The standard interface design allows for direct replacement of mainstream domestic vacuum circuit breakers without additional modification.
