Protection Relays & Systems are used to protect electric systems against serious damages caused by over-current, over-voltage and other similar electrical faults. One of the most common protection relays and systems available in the market is the WD25-022. This unit is designed to protect against over-voltages and prevent a catastrophic failure of the system.

The WD25-022 is an adjustable over-voltage protection relay which is designed to trip when the voltage across the protected load exceeds the predetermined threshold value. The unit has two adjustable adjustment dials that allow the user to select the required trip level value between 6 and 600 volts. It is also equipped with an adjustable trip time delay which can be adjusted from 0.1 to 20 seconds, allowing the user to select the amount of time the unit has to recognize the over-voltage and initiate a trip.

The WD25-022 protection relay is typically used in industrial, commercial, domestic and military applications to prevent system damage caused by over-voltage spike or abnormally high voltage. It is mainly used to protect the electrical systems from sudden surges or unusual high voltage levels caused by fault current. The unit also serves to protect against sustained over-voltage conditions such as mis-operation of an electric system or faulty wiring.

The WD25-022 is one of the most efficient and reliable protection relays & systems available in the market. It is designed with superior components and features that make it much easier to install and operate. The unit has a simple connection system with clearly marked terminals for each connection. It also features a front mounted thermal switch that activates the trip during an over-voltage, further increasing the safety of the system.

The WD25-022 protection relay is built using solid-state components which can effectively protect against both normal and over-voltage conditions. The unit also has a built-in test, to help check the unit and provide assurance that it is in proper working order. This feature also allows for manual re-setting of the trip level. Additionally, the protection relay is also equipped with a thermal shutdown circuit that automatically shuts off the unit in case of a prolonged over-voltage condition.

The WD25-022 is an ideal solution for protecting electrical systems against over-voltage and other electrical faults. It is designed for ease of installation and maintenance and its performance can be reliable over long periods of time. The unit also offers greater flexibility as it can be adjusted to suit the particular needs of the system being protected. The solid-state components of the unit also offer a higher level of protection against electrical faults. All these features make the unit a preferred choice for offering protection against over-voltage.
