The ES-27/59 ac voltage relay provides voltage monitoring and protection and may be specified for use in single-phase or three-phase applications. The ES-27/59 provides undervoltage and overvoltage protection.
A plug-and-play retrofit relay that replaces legacy GE PVD21B and PVD21D differential voltage relays while fitting directly into existing M1 GE PVD cases for simplified bus protection upgrades.
An overvoltage relay that detects excessive voltage conditions and helps protect electrical systems and connected equipment from voltage-related damage.
A three-phase time overcurrent relay with voltage restraint that adjusts overcurrent response based on system voltage levels to improve protection, coordination, and performance in generator and power system applications.
A three-phase and neutral time overcurrent relay with voltage restraint that adjusts overcurrent response based on system voltage levels to improve fault protection, coordination, and generator application performance.
A single-phase time overcurrent relay with voltage restraint that improves coordination during fault conditions by adjusting overcurrent response based on system voltage levels.
A three-phase time overcurrent relay with voltage control that combines time overcurrent protection and undervoltage supervision to improve fault detection and coordination in power system applications.
A two-phase and neutral time overcurrent relay that provides dependable phase and ground fault protection for distribution, industrial, and utility power system applications.
