BE3-GPR GENERATOR PROTECTIVE RELAY
Behind-the-Panel Mounting Semi-flush Mounting

Basler Electric’s BE3-GPR generator protective relay offers multiple protective features in a single package. Its microprocessor-based design provides high accuracy, reliability and repeatability. It is extremely easy to set up with an IBM compatible PC or from a menu-driven settings screen or from thefront panel. The digital readout makes calibration quick, easy, and accurate without the need to bench test the relay to verify settings.

BE3-GPR

DESCRIPTION
BE3-GPR (Generator protective relay) utilizes microprocessor-based technology to provide total generator protection in a single package. This microprocessor design allows for exact set point adjustment and precise generator system protection. BE3-GPR provides multiple functions in a single case, and that adds up to significant installation and setup savings.BE3-GPR allows for direct setup via a PC for easy, fast setup. Low sensing burdens mean that BE3-GPR does not require dedicated PTs and CTs.
