Industrial CV3125X 125A 3-Pole 240 V Circuit Breaker Potential Transformer

Meet the Industrial CV3125X 125A 3-Pole 240 V Circuit Breaker — a rugged, reliable protection device built for demanding electrical environments. With Part Number CV3125X, this three‑pole breaker delivers dependable overcurrent protection for critical industrial circuits, helping you minimize downtime and protect valuable equipment.

Engineered for three‑phase 240‑volt power distributions, the CV3125X thrives in challenging settings like manufacturing floors, heavy machinery panels, motor control centers, and industrial switchgear. The 125 A current rating makes it an excellent choice for feeders and branch circuits that require solid protection without oversizing the system.

• Current rating: 125 A
• Poles: 3-Pole (three‑phase protection)
• Voltage rating: 240 V
• Part number: CV3125X
• Ideal use cases: protect industrial feeders and control circuits in panels, switchgear, and motor control centers

This breaker isn’t just another component—it’s a deliberate choice for reliability and uptime in serious industrial environments. The three‑pole configuration ensures balanced protection across all phases, helping prevent damage from overloads or short circuits and supporting safe startup and operation of motors and other heavy loads.

Practical deployment tips:

• Pair the CV3125X with the appropriate load profile and ensure the surrounding panel labeling reflects the 125 A, 3‑pole, 240 V configuration.
• When replacing existing gear, opt for a like‑for‑like current rating and configuration to maintain proper protection coordination.
• Install within a properly rated enclosure, observing clearances and all applicable electrical codes and standards.
• Use in industrial power distributions where protection and measurement setups may involve potential transformers, ensuring compatibility with your protection scheme.
