JY-6 Three phase low voltage relayDetailed product description：

Purpose:

JY-6 three-phase low-voltage relay is used in relay protection lines of power systems as a voltage blocking component.

Relay model name:
Example: The order code for a three-phase low-voltage relay with an auxiliary DC working voltage of 110V is JY-6/110V.



Working Principle:
The JY-6 three-phase low voltage relay has three low voltage circuits inside, which are set by dial switches for convenience and intuitiveness. Use three outlet relays separately (see relay principle diagram and internal wiring diagram of relay); It exists independently of each other. The schematic diagram of each circuit of the relay is as follows: (see Figure 1)



Usage:
Users can easily grasp the usage of the relay based on the internal wiring diagram (i.e. Figure 2) and schematic diagram provided on the relay panel.
The LED used to indicate the power supply (marked as ± 12V) on the panel after connecting the DC power supply to terminals 112 and 114 emits light. Otherwise, it indicates a fault in the DC circuit of the relay.
The action value of the relay is set by the dial switch on the panel, and the three low-voltage circuits are debugged and set separately. First, put a low voltage circuit into operation, and the setting value on the dial is the low voltage operating value, with an operating range of 10-99V and a low voltage outlet. After the relay is activated, the UA LED on the panel lights up. The other two circuits UB and UC of the relay operate similarly to the above, with a low voltage outlet. After the relay is activated, the light-emitting diodes labeled UB and UC on the panel will light up.
