REF541KM115AAAA | ABB | Multifunctional Feeder Protection

REF541KM115AAAA | ABB | Multifunctional Feeder ProtectionProduct Overview The REF541 (REF541KM115AAAA) is a high performance, multifunctional feeder protection and control terminal designed for advanced medium voltage distribution systems. As a key Intelligent Electronic Device (IED) in the ABB power protection portfolio, the REF541 (REF541KM115AAAA) integrates comprehensive protection, measurement, monitoring, and control capabilities within a single numerical unit. This revision A module is engineered to

This means no local I/O module can be located more than 4 slots away from the chassis power supply to ensure adequate backplane voltage stability for the safety logic

The 84140-01 ensures that critical machinery diagnostics do not interfere with active protection

The DSQC503A (3HAC18159-1) ensures that multi-axis movements are executed with fluid precision

minimizing signal noise and latency

Operating within the Yokogawa CENTUM distributed control system framework
