Compact Circuit Breakers – Understanding the Tripping Characteristics
Low-voltage circuit breakers are used to protect low-voltage installations, cable lines, and connected equipment against overloads and short circuits. On the market, we encounter two different types of compact circuit breakers: those with thermo-magnetic (electromechanical) trip units and those with electronic trip units.
Thermo-magnetic compact circuit breakers operate based on a bimetal element and an electromagnetic trip mechanism. In the case of an overload current, due to the physical properties of the bimetal, it gradually bends until the circuit breaker trips. In the event of a short circuit, a strong magnetic force is generated, which activates the electromagnetic trip mechanism.
Kompaktni odklopniki – Razumevanje izklopnih karakteristik
Nizkonapetostni odklopniki se uporabljajo za zaščito nizkonapetostnih inštalacij, kabelskih vodov in priključenih naprav pred preobremenitvami in kratkimi stiki. Na trgu srečamo dva različna tipa kompaktnih odklopnikov: tiste s termomagnetnim (elektromehanskim) sprožilnikom in tiste z elektronskim sprožilnikom.
Termomagnetni kompaktni odklopniki delujejo na osnovi bimetalnega elementa in elektromagnetnega izklopnega mehanizma. V primeru preobremenitvenega toka se zaradi fizikalnih lastnosti bimetala ta postopoma upogne, dokler odklopnik ne izklopi. V primeru kratkega stika se ustvari močna magnetna sila, ki sproži elektromagnetni izklopni mehanizem.
