1200A 4.16kV Vacuum Circuit Breaker, 41kA, ML-17, Drawout
The General Electric GE-PV-ML17-350-1200A medium voltage vacuum circuit breaker is a high-performance protective device designed for switchgear applications requiring reliable fault current interruption. This vacuum circuit breaker is rated for 4.16 kV nominal voltage class with a continuous current capacity of 1200A and an interrupting rating of 350 MVA (41 kA symmetrical short-circuit current). The unit features a Basic Impulse Level (BIL) rating of 60 kV, ensuring robust insulation coordination against transient overvoltages. The ml-17 stored energy spring operating mechanism provides dependable closing and opening operations with proven reliability across thousands of duty cycles. Utilizing vacuum interrupter technology, this breaker delivers clean, maintenance-friendly arc interruption with extended contact life compared to traditional air-magnetic designs. Available in drawout configuration, the breaker integrates seamlessly into standard metal-clad switchgear assemblies. Fully compliant with ANSI C37.06, IEEE C37.04, IEEE C37.09, this circuit breaker meets or exceeds all applicable safety and performance requirements. Ideal applications include power distribution in industrial plants, utility substations, commercial buildings, hospitals, data centers, mining operations requiring medium voltage circuit protection. This circuit breaker is supported by readily available renewal parts and comprehensive technical documentation, ensuring long-term serviceability and reduced total cost of ownership for medium voltage switchgear installations. Integrated safety interlocks prevent unsafe operations during breaker insertion, removal, and racking procedures.
