CIRCUIT BREAKERS FOR EQUIPMENT
T12 Series
Thermal release
• Positively trip-free
• Reset or manual
actuation
A circuit breaker for equipment (CBE) of the T12 series is a single
pole, thermally operated device providing small size, low cost and
reliable trip-free operation on overloads and short circuits, up to the
maximum breaking capacity. It is intended primarily for protection
of motors, transformers, solenoids etc. against damage due to over-
current conditions.
The well proven mechanism is designed to open the contacts in the
event of a current flow in excess of the time/current characteristic of
the device. A bimetal strip is heated by the overcurrent and deflects,
thereby releasing the latch mechanism. The contacts will open even
if the reset button is manually held in the closed position. This is
known as the positively trip-free feature. The contacts open and
close with a snap action and the tripped state is clearly shown by the
increased projection of the reset button. After operation, the
mechanism will not latch closed until the manual reset button is fully
depressed and then released. It is impossible to ‘tease’ the contacts
by gentle pressure on the reset button.
The time which can elapse in case of an overcurrent is given by
the tripping characteristic (tripping zone). This curve is valid for a
device operating at an ambient temperature of +23°C, without
any preloading.
