Hello dear foristas, I had a problem with a 40A tetrapolar circuit breaker that practically melted in two of its inputs in the neutral and one phase, a consumption of 30A or so is applied to a 4x6mm sintenax cable. What would be better? Replace said circuit breaker with another one of better quality. The melt is SICA or place 3 bipolar circuit breakers and thus balance the loads on each one of them? Thank you

Hi. If there are three-phase loads if or if you must replace it with another one. If there are not, you can place three bipolar without problems. Adjust the terminals of the new differential well so there will be no overheating problems like the one that failed. Regards
