Thermal overload relays ..
The built-in auxiliary contacts are electrically
isolated and are therefore suitable for two
different circuits (control circuit and signal
ling circuit).
TA110DU
All relays feature facility for temperature com
pensation and phase failure protection.
The overload relays size TA110DU are
safe from finger-touch and safe from touch by
the back the hand.Thermal overload relays
T7DU, TA25DU .. The Reset button can also be
used for disconnection. are three-pole
relays which can converted from manual to
automatic reset
