Schneider V255-073749 VAMP 255 Series Protection Relay

Configured for selective current and fault monitoring in industrial power distribution topologies, the Schneider V255-073749 (V255-073749 Feeder and Motor Protection Relay) provides direct physical/electrical execution. The panel-mounted electronic assembly measures and analyzes real-time phase vectors natively at the hardware tier to initiate circuit isolation routines upon detection of current anomalies.

Hardware Specifications

Industrial Control & Drive Communications

• Profinet / EtherNet/IP Deterministic Networks and Substation Fieldbus Routing The protection relay integrates directly with high-speed substation network pathways, executing deterministic data packet delivery over localized automation buses. This communication subsystem interfaces with SCADA or DCS master architectures, allowing telemetry variables and fault-event logs to stream across the transmission loop parallel to primary protection algorithms.
• I/O Density Scaling and Processing Core Synchronization The micro-controller engine continuously samples current vectors across overhead lines, motor lines, and busbar links, processing high-density operational data points. The firmware scales logic scanning performance within the hardware matrix, allowing rapid calculations that ensure trip relay actuation coordinates precisely with field breaker thresholds under transient overload cycles.
