Fault Clear Auto Reclosers from Sunwa

Reclosers

FAULT CLEAR® Auto Recloser is deployed in the overhead power distribution line as a protection device, and its functions and performance are tested in accordance with IEEE C37.60 / IEC 62271-111 at a third-party laboratory. Togami Electric has experiences in power utility business by supplying switches over 90 years.

Features

Interchangeability

  • FAULT CLEAR can replace currently installed reclosers on the utility poles. Simply disconnect the control cable from the installed recloser, and connect to FAULT CLEAR.
  • FAULT CLEAR can be used as a standard three-phase or Triple/Single recloser. The recloser ratings and construction apply to both applications for a more robust product and long life.

Compatibility

  • FAULT CLEAR can be connected with a SEL-651 R2 controller through a standard 32-pin control cable for three-phase or Triple/Single application. The single phase FAULT CLEAR unit is compatible with the SEL-351 RS controller with a 10-pin control cable.

Enhancing Reliability In Grid Operation

  • FAULT CLEAR consists of three independent solid dielectric interrupters that enable operation by phase. Single phase operation on a three phase system increases reliability for the overhead distribution grid operation.

Construction

  • FAULT CLEAR has 6 voltage sensors and 3 current sensors built in.
  • FAULT CLEAR is designed to have long service life by selecting reliable materials and parts.
  • Bushings are made of an epoxy body with silicone sheds for high UV environments.
  • Recloser frame and mounting bracket are made from aluminum for use in high industrial pollution and salt-spray environments.
