Single Pole Thermal Circuit Breaker 4A Schurter T12-211R

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 overcurrent 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, withouth any preloading.
