DESCRIPTION
Available either in standard or snubberless
version, the BTA/B TB 1 0 tr i a c series is suitable for
general purpose AC swi tching. They can be used
as an ON/OFF function in applications such as

static relays, heating regulation, induction motor
starting circuits... or for phase c ontrol operation in
light dimmers, motor speed controllers, ...
The snubberless version (W suffix) is specially
recommended for use on inductive loads, thanks
to their high commutation performances.
By using an internal ceramic pad, the BTA series
provides voltage insulated tab (rated at 2500 V
RMS) complying with UL standards (File ref.:
E81734).
