3P 16-125A 400V AC MCCB

The MCCB is suitable for power supply lines of power equipment such as machine tools, fans, and water pumps in factories, as well as large three phase electrical equipment, such as central air conditioning and elevators in shopping malls and office buildings. The 8kV rated impulse voltage can withstand sudden voltage changes in the power grid, and the 25kA breaking capacity can quickly cut off the current in case of short circuit faults, preventing accidents from escalating. Compliance with the IEC 60947-2 standard ensures the product's standardization and reliability in design, manufacturing, and performance, making it universally applicable worldwide and compatible with other electrical equipment conforming to this standard.

High Voltage Impulse Protection: With an 8kV rated impulse voltage, the YRO 3P 16-125A 400V AC MCCB has strong anti interference capability in complex industrial electrical environments, effectively preventing instantaneous high voltage caused by lightning strikes, power grid switching, etc., from damaging the equipment, reducing equipment failure rates, and improving production continuity and stability.
International Standard Certification: Compliance with the IEC 60947-2 standard means that the circuit breaker has been tested and verified for safety, reliability, and performance indicators, ensuring international universality and compatibility.

Terminal Block Design: The terminal block is designed for high current carrying capacity, using high quality copper alloy materials with a specially treated surface to improve conductivity and oxidation resistance. The connection method of the terminals is convenient and quick, adapting to different specifications of wire and cable connections. At the same time, it has good tightening performance, ensuring stable and reliable connection between the wires and terminals during long term operation, reducing contact resistance, and preventing safety hazards such as heating and sparking caused by loose wiring.
