1 / 7Circuit Breaker
MCB 4P AC 6鈥?3A Circuit breaker
The Cnsoltree 4 Pole MCB delivers complete protection for three-phase four-wire (3P+N) systems by simultaneously isolating all three phase conductors and the neutral 鈥?the highest level of circuit isolation available in a miniature circuit breaker. It is the code-compliant choice for TN-S and TN-C-S earthing systems where neutral switching is required, including commercial buildings, data centres, hospitals, and industrial facilities with sensitive electronic loads. The 4-pole design eliminates the risk of neutral voltage rise during asymmetric faults, protecting downstream equipment from damaging overvoltage. Available from 6A to 63A with B, C, and D trip curves to match any load profile.
