CNC AC 4 Pole MCCB 63A to 800A Molded Case Circuit Breaker YCM7 | Durable Electrical Protection

CNC YCM7 AC 4 Pole MCCB (63A to 800A)

The CNC Electric YCM7 4 Pole MCCB protects 3-phase + Neutral power systems from overload and short circuits. All four poles (L1, L2, L3 and N) trip together, so the Neutral is fully isolated as well. That makes it a strong choice for installations with unbalanced loads, generators, and solar inverter systems where Neutral isolation matters.
