Teknic offers Teknic ABL MPCBs in collaboration with ABL SURSUM Germany. These offer solutions for fuseless installations to protect motors and the wiring against overloads and short circuits. The product MS Series combines the function of switching, protection, and signalling in a single compact unit. Due to the modular design principle of the product various accessories such as under voltage release, shunt release, auxiliary contacts, connectors etc. can be added depending on the application. The main features are trip free mechanism, phase failure sensitivity, current rating upto 32 A, reliable switching of motors causing any nuisance trip due to starting inrush current, adjustable thermal elements, main switch function etc

The TR11 circuit breaker for equipment (CBE) is a single pole, push to reset, thermally operated overload protector, providing reliable trip free operation on overloads and short circuits within the maximum breaking capacity. The trip mechanism is of a latch type and a high contact force can be maintained until the unit trips. This prevents contact bounce and reduces the risk of contact wielding. Main applications are protection of single-phase motor transformers, solenoids etc. against damage due to over current conditions.

OperationThe mechanism of the circuit breaker is designed to open the contacts in the event of a current flow in excess of the rated current according to the time/current characteristics of the device. A thermo bimetal strip, which has the advantage of being immune of high inrush currents and line transits, is heated by over current and deflects thereby releasing the latch mechanism. The contacts open even if reset button is manually held in the closed position. The is known as trip free mechanism. The contacts open and close with a positive snap action and the tripped state is clearly indicated by the extended projection of the reset button.
