Basler Electric BE1-700 Digital Protective Relay

Basler Electric BE1-700 Digital Protective Relay is a compact, microprocessor‑based protective relay designed for multifunction power-system protection. Available as BE1-700C (current‑only) or BE1-700V (voltage‑only) in a panel‑mount, non‑drawout enclosure, it supports a broad set of IEEE device functions (24, 25, 27, 43, 47, 59, 60, 62, 79, 81, 101) and combines voltage or current protection with frequency and control protection, including breaker‑failure protection. The BE1‑700 leverages BESTlogicPlus configuration, enables system analysis through oscillography, sequence‑of‑events, and metering data, and provides two independent communication ports with Modbus protocol support for integration with distributed control systems; BESTCOMSPlus software is available to configure and monitor the device. It is suited for bus, feeder, generator/motor protection, and cogeneration applications, delivering protection and control elements that can be selected from preprogrammed logic schemes or user‑defined logic to match specific protection schemes while occupying minimal panel space.
