Voltage relay RE VA-63A with current protection Voltage monitoring relay V40A Overvoltage protection
Let's analyze the single-phase voltage relay RE VA-63A with current protection and the voltage control relay RE V-40A from the Rostock-Electro company. This voltage monitoring relay provides the following: overvoltage protection, undervoltage protection, overcurrent protection (for VA-63A), phase imbalance protection and zero loss protection. This voltage relay is mounted on a DIN rail and takes up 2 slots. These voltage relays can operate with floating frequency power from generators. Relays do not respond to rapid small voltage sags.
