Description

Product Overview

The GE F650BABF2G0LOSHE is a Multilin F650 feeder protection relay and bay controller, integrating protection, control, metering and fault recording for medium-voltage distribution feeders, capacitors and busbar systems. This multifunctional relay delivers phase/ground overcurrent, directional overcurrent, over/undervoltage, over/under frequency and four-shot auto-reclosing logic, with breaker failure protection and cold load pickup functions. It resolves equipment damage and prolonged outages caused by short-circuit, overload and voltage disturbances on utility and industrial power networks. Substation automation engineers and reliability teams rely on this unit for new substation build and spare replacement. The front graphical LCD supports local setting adjustment and fault viewing, while multiple communication options enable seamless connection to SCADA systems. Timestamped sequence-of-event records and oscillography help engineers quickly locate root causes of power system faults. Word count overview:173

Application Scenarios

• Industrial Substation Feeder Protection: This relay serves as main protection for medium voltage feeders supplying factory loads. The F650BABF2G0LOSHE detects short circuit and overload faults, trips breakers and performs auto-reclose for transient faults to reduce downtime.
• Capacitor Bank Switching Control: Installed for power factor correction capacitor banks, it includes 2nd harmonic restraint to avoid false tripping during capacitor energization and monitors voltage for bank protection.
• Utility Distribution Substation Bay Control: The unit combines protection, breaker control and metering in one device. It transmits real-time electrical data and fault alarms to SCADA, supporting remote substation unmanned operation.
