Schneider VAMP 55 PowerLogic Voltage Protection Relay

Schneider VAMP 55 PowerLogic Voltage Protection Relay is a multifunction numerical relay designed for voltage and frequency protection in low- and medium-voltage power systems. It continuously monitors system voltage and helps protect electrical equipment against abnormal voltage conditions that can affect the stability and reliability of the network.

The relay offers flexible voltage measurement with four configurable voltage inputs, allowing it to be adapted for different protection schemes, including phase voltage monitoring, zero-sequence voltage measurement, and synchronism check applications. Along with protection functions, it also provides control, metering, event recording, and live measurements in a single compact unit.

VAMP 55 features an intuitive user interface with a clear LCD display, programmable LEDs, front-panel function keys, and a built-in single-line diagram mimic. It is suitable for industrial plants, utility substations, renewable energy systems, and OEM switchgear where dependable voltage protection is required.
