Porduct Overview

The EKM7 series high voltage molded case circuit breaker is specifically engineered to cater to the requirements of power distribution networks operating at AC 50/60Hz. It boasts a rated insulation voltage of 1200V, providing dependable protection for circuits with rated voltages ranging from 690V to 1140V, and a rated current of up to 630A.

This circuit breaker is well-suited for infrequent circuit switching and occasional motor starting. It effectively guards against overloads, short circuits, overvoltage, and undervoltage, ensuring the safety and stability of power lines.

Furthermore, the EKM7 series high voltage molded case circuit breaker adheres to the IEC60947-2 standard, ensuring its quality and performance.
 

  • High mechanical life and electrical life.
  • Short arcing distance: standard arc suppression cover and three-layer free metal partition to avoid secondary system failures caused by arcing during disconnection.
  • Super current limiting capability.
  • Super insulation performance, electrical clearance and creepage distance comply with UL489 standard.
  • Reverse inlet line without capacity reduction.
  • Anti-humidity, heat, salt spray, and mold resistance.
  • New single breakpoint structure, more stable and reliable than double breakpoint structure.
