Is there any direct acting device (Shunt Trip coil or Under Voltage coil) is required with NSX's/CVS's vigi module to trip the MCCB ?

Shunt Trip Coil/UV Coil are not required in MCCB for the tripping operation with Vigi Module. Means the Vigi Module for earth leakage protection will trip the MCCB without the usage of Shunt Trip or Under voltage coil if it senses the fault.
The Vigi Module has an inbuilt lever that push the trip mechanism of MCCB in case of Earth leakage fault.
