Industrial PVC-400-AR Three Phase Voltage Relay

R-K Electronics' PVC-400-AR is an industrial three-phase voltage relay designed to monitor voltages across all three phases in a three-phase electrical system. The PVC-400-AR model identifies this device within R-K Electronics' lineup of voltage relays and positions it for use in control panels and industrial power-distribution setups where reliable phase sensing is required. This relay is intended for industrial environments where accurate monitoring of three-phase supply is essential for maintaining equipment performance and automated control sequencing. By providing dedicated three-phase voltage sensing, the PVC-400-AR serves as a modular component in electrical panels, enabling integration with protection and automation schemes that depend on phase voltage information.
