Miniature Circuit Breakers (MCB) Earth Leakage Circuit Breaker (ELCB)

Miniature Circuit Breaker

The Miniature Circuit Breakers (MCB) are current-limiting devices. These MCB’s force a fast and efficient extinguishing of the arc, which results in a limiting of the short circuit current before it can go up to its peak. The time tE (tripping response time between the short circuit occurrence and the separation of the contacts) is extremely short, due to the use of the electromagnetic principle in the magnetic trip mechanism. The oscilloscope reading shows time tE = 0.7 msec. The fast and wide contact separation causes the rapid elongation of the arc, which establishes a sharply rising arc voltage across the contacts. Parallel to that, the arc is guided between special plastic plates to the arc chamber by the “arc guide”. In the arc chamber, the electrodynamic and thermodynamic forces continue the established movement of the arc to the plates of the miniature de-ion grid, which extinguishes it. The full burning voltage UB = 340 V is reached after 1.4 msec. The strong rising arc voltage works as an additional impedance, which limits the short circuit current (I = 4.5 kA) and extinguishes it far before (4.3 msec) the natural waveform zero crossover. The selectivity diagram shows the let-through-∫i2 dt (Joule/Energy Integral) of a full sine half wave (1) and MCB’s (2, 3, 4). All the shown values of the Joule-Integral (let-through-∫i2 dt) are maximum values of the MCB’s switch-off time, which only occur when the short circuit current develops at a moment of the sine half wave where the angle is between 600 and 900. In addition, the diagram shows the melting curve (let-through-∫i2 dt) of fuses according to DIN VDE 0636. The crossing of the MCB – and fuse – trip characteristics show the short circuit current up to which selectivity is still maintained. The melting curve of the fuses represents the minimum value. For example, the crossing of the curves of a B 16 A MCB and a 35 A fuse is 1.5 kA. The value for a 100 A fuse is about RA. That means, that the MCB will trip up to these short circuit currents and the fuse stays intact. The MCB’s, due to their strong current and energy limiting capabilities, meet all the requirements for the highest current and energy limiting Class 3 according to DIN VDE 0641 Part 11 / EN 60898 / IEC 60898. As a matter of fact, the real let-through values are much lower.
