Current relay 4 functions 2x2P 16A - EPP-620

Purpose: The current relay is used to control the current value in the measured circuit by switching contacts in case the current value exceeds the specified threshold values both above and below.

Operation: The relay is designed to operate with a current transformer with a secondary current of 5A. The primary circuit of the transformer is connected to the current measuring circuit, while the secondary circuit is connected to the relay's measurement terminals. The relay operates according to one of the four working functions. The function is selected by adjusting the FUNC potentiometer's arrow to the chosen mode indication [A, B, C, or D]. The current thresholds are set using potentiometers - lower Imin and upper Imax. The exceeding of the measured current value causes the appropriate contacts to close according to the selected working function. The contact closes with a delay defined by the potentiometers T1 (for contact R1) and T2 (for contact R2). The closure of the contacts is indicated by the lighting of the respective Imax and Imin LEDs.

Technical specifications:

• Power supply 230V AC
