Rapid start up – a completely deenergised EcoLink can be closed onto the fault, harvest energy and trip within a few cycles. The EcoLink''s supercapacitor array gathers sufficient trip energy to allow similar responses to existing fuses. The bigger the fault, the faster the trip. Lighter weight – the EcoLink only weighs only 7.4kg.

In the capacitor-resister circuit (capacitive energy storage system) shown as Fig. 3.12a, the electrical energy 0.5CV 0 2 (V 0 initial charging voltage) is stored in a capacitor and then
The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the segmentation fault has a large current (excessive current will melt the
