Introduction

The new class of single phase auto-recloser

By eliminating regular maintenance and utilising line voltage as power supply, the new Compact Modular Recloser (CMR) addresses common problems of obsolete hydraulic reclosers. The compact recloser is fully rated for voltage systems up to 27 kV and features a complete insulated housing that covers all live parts. The lightweight device permits easy installation and fast commissioning, plus the ability for wireless firmware and configuration updates.

             

Key Features

Fully integrated self-powered system

  • Power supply using line voltage
  • Rechargeable battery for back-up power
  • Magnetic actuated vacuum interrupter
  • Integrated protection relay and controller
  • Flexible mounting options 

Intelligent

 

  • Wireless connectivity
  • GPS time reference
  • SCADA capability (future)
  • Voltage and current measurement
  • Fault passage indication (FPI)
  • Comprehensive event log
  • Full range of TCC curves

Compact

 

  •  Light weight (20kg excl. bracket)
  • Simple and quick to install

Reliable and maintenance free

 

  • The new auto-recloser is suitable for all sites, even those with inconsistent or no line current. Featuring fully configurable protection and four operations in a sequence, the unit presents the ideal solution for sectioning faults on long rural distribution lines.
  • The system design facilitates an uninterrupted operation for most efficient service. Unlike hydraulic reclosers, the auto-recloser has no need of periodic inspection and maintenance.
