Modular recloser CMR

hydraulic-magneticinsulatedsingle-phase

CMR is offered with voltage ratings from 17.5 - 38 kV, rated short-time withstand current up to 12.5 kA, rated continuous current up to 630 A, and lightning impulse (BIL) up to 170 kV. As a direct substitute for traditional, single-phase, hydraulic reclosers, the type CMR allows for reduced maintenance with only the rechargeable battery pack having to be replaced. Wireless communications enables in-service reconfiguration and downloading of the event log and load profile. By eliminating regular maintenance and utilizing line voltage as power supply, the new modular auto-recloser addresses common problems of obsolete hydraulic reclosers. The compact recloser is fully rated for voltage systems up to 38 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. The CMR conforms to the revelant sections of the following standards: IEC 62271-111 (2012) / IEEE C37.60. Application: Lightweight, reduced-maintenance alternative to hydraulic reclosers. Fully integrated self-powered system: • Power supply using line voltage • Rechargeable battery for backup power • Magnetic-actuated vacuum interrupter • Integrated protection relay and controller • Flexible mounting options. Intelligent: • Wireless connectivity • GPS time reference • SCADA capability • Voltage and current measurement • Fault-passage indication (FPI) • Comprehensive event log • Full range of TCC curves. Compact: • Lightweight 48.5 lbs (22 kg) excluding mounting bracket • Simple and quick to install.
