| Note: 1. Y the function is available, N the function is not available |
| 2. In the circuit of three phase four wire, the relay which have no phase sequence protection function can be used to protect single phase or two phase circuit. |
|
| 3. All models relay can be adjusted in 220V/230V/240V or 380V/400V/415V except RV2 -07, RV2 -08 |
