Schneider Electric v40-029797 Motor Protection Relay

Schneider Electric Vamp 40 v40-029797 is a compact feeder and motor protection relay in the Vamp 40 family, engineered for MV feeders, motors and capacitor banks. It provides two application modes—feeder protection and motor protection—so protection logic can be referenced to In for feeders or Imot for motors. Designed for overhead line feeders, cable feeders, motor feeders, capacitor banks and reactors, it comes in a slimline case suited to tight installations. The device delivers comprehensive measurements and protection functions, including phase and residual currents, voltages, frequency, current imbalance, active/reactive power and energy, plus power quality analysis with harmonics up to the 15th order and THD on both current and voltage, with arc protection and 200 event sequence recordings for post-fault analysis. For integration, VAMP 40 supports a broad set of communication protocols (IEC 60870-5-101/103, Modbus TCP/RTU, Profibus DP, TCP/IP, DNP3, SPA-bus, IEC 61850) and can be configured with Schneider’s VAMPSET software via an RS-232 interface. Auxiliary power input is wide (19–265 V ac/dc, 50/60 Hz), enabling flexible installation with various power systems. In Schneider Electric’s catalog, Vamp 40 is described as discontinued, but the v40-029797 part number identifies a Vamp 40 Feeder/Motor Protection Relay configuration used in MV protection schemes.
