SS22S

Star-delta relay

MFT SS22S

S - Star-delta start-up

When the supply voltage U is applied, the star-contact

switches into on-position (yellow LED illuminated) and

the set star-time Y begins (green LED U/t flashes).

After the interval Y has expired (green LED U/t illumi-

nated) the star-contact switches into off-position

(yellow LED not illuminated) and the set transit-time

(Y → Δ ) begins. After the interval Δ has expired the

contact for the delta-contactor switches into on-

position (green LED U/t illuminated). To restart the

function the supply voltage must be interrupted and

re-applied.
