MCB YCB9 4P

The YCB9 (4P) circuit breaker is the essential line of defense for protecting 3-phase electrical circuits. It is engineered to provide dual protection: thermal protection against overloads and magnetic protection against short circuits. With its 4-pole design, it ensures the simultaneous disconnection of all three phases and the Neutral line, providing total safety for industrial equipment and main distribution boards. ⚡ Key Features: Full 4-Pole Protection (4P): Guarantees the disconnection of the Neutral line along with the phases, protecting the system from reverse current risks and ensuring total isolation during maintenance. High Breaking Capacity: Built to handle sudden short-circuit currents efficiently, maintaining cable integrity and preventing electrical fires. Long Operational Lifespan: A robust internal mechanism designed for thousands of switching cycles under full load, featuring high-quality contact points. Modular Design: Easily mounts on a standard 35mm DIN Rail, making it compatible with most international distribution boards. Clear Status Indicators: A visual window clearly shows the breaker status (ON/OFF) for easy monitoring and diagnostics. 🛠️ Technical Specifications: Brand: CNC Electric. Model: YCB9 Series. Number of Poles: 4P (3-Phase + Neutral). Trip Type: Thermal-Magnetic. Breaking Capacity (Icn): Available in (4.5kA, 6kA). Tripping Curve: Available in (B, C, D Curves) to suit various load types. International Standards: IEC/EN 60898-1 / CE Certified.
