2000A 7.2kV Vacuum Circuit Breaker, 33kA, Spring Mech
Engineered to meet the highest industry standards, the Eaton VR-Series+ EATON-7.5VHK-VR+500-2000A vacuum circuit breaker provides superior arc interruption and electrical isolation for medium voltage systems. This vacuum replacement breaker is rated for 7.2 kV nominal voltage class with a continuous current capacity of 2000A and an interrupting rating of 500 MVA (33 kA symmetrical short-circuit current). The unit features a Basic Impulse Level (BIL) rating of 95 kV, ensuring robust insulation coordination against transient overvoltages. The 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. This unit is designed as a direct replacement for ITE/ABB 7.5VHK-500 breakers, enabling modernization of existing switchgear installations without costly cell modifications. Available in drawout configuration, the breaker integrates seamlessly into standard metal-clad switchgear assemblies. Fully compliant with IEEE C37.59-2018, ANSI C37.09, this circuit breaker meets or exceeds all applicable safety and performance requirements. Ideal applications include replacement of legacy ite/abb hk and vhk air-magnetic circuit breakers in existing metal-clad switchgear, utility substations, industrial power distribution, commercial building medium voltage systems. 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.
