The K8AB-PH1 current monitoring relays accept three-phase supply voltage, measure single phase current, and output a signal when the detected current surpasses the operation thresholds. The relays can be used to monitor system current, overcurrent, over-voltage, under-voltage on single-phase AC circuits.

Composed of the main body and one or two functions, the K8AB-PH1 relay offers various protective functions by combining the main body with several optional functions. Main body can be used for over-current protection, phase failure protection along with time-delay functions.

The operating principle of the K8AB-PH1 relay is based on using the current measured. It monitors the three phase current whenever the over-current protective function is set. Additionally, the K8AB-PH1 can be used for under-voltage protection and over-voltage protection by detecting the voltage across line-line. Furthermore, phase failure protection can be provided when the relay detects the current across line laid.

The K8AB-PH1 relay comes with an adjustable threshold. A variety of functions are available to enable the user to customize the relay’s operation. For example, for applications that demand a greater voltage protection range, a two-phase protection setting can be utilized.

The K8AB-PH1 current monitoring relays include an adjustable delay timer. The timer is set to activate the relay when the current is above the setpoint for a certain amount of time. This adjustable delay timer feature is beneficial when monitoring motors. It prevents false trips that occur when motors start up.

The K8AB-PH1 relays outputs a relay contact when the monitored value changes. This feature is useful in applications requiring a direct action. The K8AB-PH1 offers a variety of outputs including dry contact, electronic contact, resistor output, and DIL contact, depending on the model of the relay.

In summary, the K8AB-PH1 current monitoring relays offer a range of features suitable for use in various applications. It can protect single-phase AC circuits from over-current, over-voltage, and under-voltage conditions. Additionally, it includes adjustable threshold, adjustable delay timer, and relay output options to enable flexibility.
