VAMP V57F4-AAA2BBA Feeder Protection IED

Product Description

V57F4-AAA2BBA belongs to VAMP 57 series arc flash and feeder protection relay, developed by VAMP (now part of Schneider Electric). It is a multifunctional intelligent electronic device for medium voltage switchgear protection, monitoring and control. The ordering code defines: wide auxiliary power 48–230V AC/DC, 24V digital input nominal voltage, 4 current and 4 voltage measurement inputs, 16 digital inputs and 8 digital outputs plus 1 signal fail relay, equipped with RS485 communication interface. This relay integrates arc flash protection, overcurrent, earth fault, voltage protection and disturbance recording. 19-inch panel mounting, with high-speed arc detection capability, conformal coated PCB option, strong EMC performance for harsh substation environment.
