CNC AC 3 Pole MCCB 32A to 1250A Molded Case Circuit Breaker | Reliable Overload & Short-Circuit Protection

CNC AC 3 Pole MCCB: Molded Case Circuit Breaker (32A to 1250A)

CNC Electric 3 Pole MCCBs give heavy-duty protection for 3-phase power systems. They trip automatically on overload and short circuit, which protects expensive equipment, cables, and panels from damage and fire. The rugged molded case and wide current range make them a fit for anything from small commercial panels to large industrial main incomers.
