Description
Overcurrent relay (often bundled with AVR systems).
Did you know
- The Basler Electric BE1-50/51 series of overcurrent relays, which are microprocessor-based, were first introduced around April 1992. This series was designed to replace older electromechanical relays, such as the ABB (Westinghouse) type CO relays.
- The BE1-50/51 is a self-powered, single-phase, time/instantaneous overcurrent relay within Basler Electric's protective relay systems. It sits alongside other BE1 series relays like the BE1-50 (instantaneous overcurrent) and BE1-51 (time overcurrent), with the 50/51 model combining both instantaneous and time-delayed trip functions.
- The BE1-50/51 is notable for being self-powered directly from the system current, eliminating the need for an external power source. It offers flexible pickup settings and multiple field-selectable time characteristics, allowing for tailored applications and coordination with various power system components.
| Model | Function | Power Source | Time Characteristics | Reset Function |
|---|---|---|---|---|
| BE1-50/51 | Time and Instantaneous Overcurrent | Self-powered (from CTs) | 15 popular, field-selectable | Field-selectable instantaneous or integrating reset |
| BE1-50 | Instantaneous Overcurrent | Self-powered (from CTs) | N/A (instantaneous) | N/A (instantaneous) |
| BE1-51 | Time Overcurrent | Self-powered (from CTs) | 16 field-selectable | Models available to replicate decaying reset of electromechanical relay disks |
