Protection Relays
Metaltex DIN-rail protection relays safeguard motors, machinery, and electrical systems against phase, voltage, and current anomalies. The range includes the DFF3 and DFF5 analog lines for three-phase monitoring—covering phase loss, phase reversal, asymmetry, and undervoltage/overvoltage functions—as well as the DFD digital series featuring an LCD display for parameter setting, and the RPV and DMV families for automatic undervoltage/overvoltage monitoring and control in single-phase or DC networks. Rounding out the portfolio is the DCI line, which monitors current to prevent mechanical jams and overloads.
