YC7VAN Overvoltage & Undervoltage Protector

The YC7VAN is a microprocessor‐based overvoltage and undervoltage protection relay for single-phase AC networks. It safeguards electrical equipment against voltage surges, drops, and overcurrent by disconnecting the load via an electromagnetic relay. The user can set thresholds and delay times; voltage measurements are displayed digitally. Settings are stored in non-volatile memory. Compatible with both copper and aluminum wires.
