Is it possible to provide electrical interlock only (using IVE) without mechanical interlock?

Mechanical interlocking system must be added to electrical interlocking to protect against electrical malfunctions or incorrect manual operations. Electrical interlocking is used with a mechanical interlocking system. Morover, the relays controlling the closing order to the “N” and “R” circuit breakers must be mechanically and/or electrically interlocked to prevent them from giving simultaneous closing commands.
