Core features

  • Improved customer reliability and lower total life-cycle costs
  • Enhanced safety with grounded tank
  • Environmentally preferred gas-free and oil-free
  • Reduced installation time
  • Reduced maintenance costs with solid outdoor cycloaliphatic epoxy, vacuum interruption with axial-magnetic field contacts and magnetic-actuator operated mechanism

SPEAR single-phase recloser control

Eaton's Cooper Power series microprocessor-based SPEAR recloser control integrates real-time valuable grid and outage data to be ported to a SCADA or feeder automation system. Complete with a separate regulated power supply, the control is automation-ready for your choice of radio. Also, tailor your digital communications performance with the user-configurable mapping of protocol DNP3. The control can be easily configured through the simple front panel display or with a laptop through a USB port on the front panel.

Protection flexibility

The two separate protection profiles include overcurrent protection, including 54 standard time-current curves available; time current curve modifiers, including minimum response time adder; high-current trip and high-current lockout sequence coordination as well as cold load pickup, Hot-line tag, fast trip disabled and reclose retry.
Specifications

Standards
