The K8AB-VW1 100/115VAC is a monitoring relay that combines current and voltage measurement with relay output. It is used in industrial applications for monitoring, protection and automatic control of AC circuits. It measures AC current, AC voltage, and can detect various faults in the circuit. The relay output can be used for protection against overloads, short-circuits, and phase failures in three-phase systems.

The device consists of two main sections, a measurement section and a relay output section. The measurement section measuresAC current and AC voltage. The current measurement is done using a shunt resistor, while the voltage measurement is done using a transformer. The shunt resistor and transformer are connected to the secondary of a power transformer, which is used to control the voltage of the measurement section. The relay output section consists of a relay coil, two sets of normally open contacts, and two sets of normally closed contacts. The two sets of contacts can be used for time delays or other control functions.

The device is capable of detecting various faults such as phase losses, overloads, and short-circuits. The device will shut down the circuit if any of these faults are detected. It can also be programmed to shut down the circuit if the current or voltage exceeds predetermined values. In addition, the device can be used for other control applications, such as lighting control and motor control.

The device includes several features that make it suitable for a wide variety of applications. It is equipped with an adjustable timer for time delays and an adjustable trip level for current/voltage protection. The device is also equipped with a jumper for manual control and a selectable automatic reset. The device is also capable of detecting single-trip and double-trip overload conditions.

The K8AB-VW1 100/115VAC provides an economical and reliable solution for monitoring, protection, and automatic control of AC circuits. Its combination of current and voltage measurement, relay output, adjustable timer, and adjustable trip level make it suitable for a wide range of industrial applications.
