Siemens time current breaker curves
WebLow voltage circuit breakers with a thermal-magnetic trip device allow for the discrimination between an overload from a fault. The thermal element acts as protection from overloading while the magnetic element is for protection from faults. This allows slow operation on overload and fast on fault. A typical time-current curve is shown in figure 6.
