Eaton's Cooper Power series VSA group electronically controlled, three-phase, automatic circuit reclosers with vacuum interrupters, provide reliable and economic overcurrent protection to meet a variety of line and substation applications for 15 kV systems (up to 1200 A continuous/ 20,000 A interrupting current). Recloser operations are programmed on the electronic control panel with accurate, preset tripping characteristics and reclosing times, enabling close coordination with other protective devices on the system. When system requirements change, program settings are easily altered with no sacrifice of accuracy or consistency. Recloser and control accessories enable further tailoring of the protective program to achieve maximum system operating flexibility.
