MCB Circuit Breaker 4P (32-125A) AC – CNC

The YCB9 (4P) breaker is the first line of defense for three-phase circuits. It provides double protection: thermal protection against overload and magnetic protection against short circuit. Thanks to its four-pole design, it disconnects the three phases and the neutral at the same time, providing complete safety for industrial equipment and main boards.

⚡ Features:

Full four-pole protection (4P): disconnects the neutral together with the phases, protecting the system from reverse currents and providing full isolation during maintenance.

High breaking capacity: withstands sudden short-circuit currents efficiently, protecting the wiring and preventing electrical fires.

Long service life: robust internal mechanism designed for thousands of switching operations under full load, with high-quality contacts.

Modular design: mounts easily on standard 35mm DIN Rail, compatible with most distribution boards worldwide.

Clear status indicators: a visual window clearly shows the breaker state (ON/OFF) for easy monitoring and diagnosis.
