Kanlux KMCCB-F-125A-4P Molded Case Circuit Breaker, 125A, 4-Pole, Ics 25kA, Icu 36kA

The Kanlux KMCCB-F-125A-4P is a high-performance molded case circuit breaker engineered to provide robust protection for electrical distribution systems. This 4-pole device is designed to handle a rated current of 125A, offering reliable performance in demanding industrial and commercial environments. By effectively monitoring electrical circuits, it serves as a critical safety component that prevents damage caused by overloads and short circuits, ensuring the integrity of your electrical infrastructure.

Advantages

This circuit breaker stands out due to its durable construction and precise technical parameters, which ensure consistent operation under various load conditions. The fixed setting design simplifies installation and maintenance, reducing the risk of accidental misconfiguration. With a high breaking capacity, it provides excellent protection against fault currents, thereby enhancing the safety of connected equipment and personnel. Its compact form factor allows for efficient use of space within distribution boards while maintaining high operational standards.

Suitable for

• Industrial power distribution panels
• Commercial building electrical systems
• Protection of main supply lines
• Large-scale electrical installations requiring 4-pole switching

This device may not be suitable for residential applications where space is extremely limited or where the specific current rating of 125A exceeds the requirements of the installation. It is also not designed for outdoor use without an appropriate protective enclosure, as it carries an IP20 rating.

Key specifications

• Rated current: 125A
• Number of poles: 4
• Ultimate short-circuit breaking capacity (Icu): 36kA at 220/230V AC
• Service short-circuit breaking capacity (Ics): 25kA at 380/415V AC
• Ingress protection rating: IP20

How to use

The Kanlux KMCCB-F-125A-4P should be installed by a qualified electrician in accordance with local electrical regulations. It is typically mounted within a distribution cabinet or switchgear enclosure. Ensure that the input and output cables are correctly sized for a 125A load and securely fastened to the terminals to prevent overheating. Once installed, the breaker can be manually toggled to control the power supply to the downstream circuit.

What to consider before purchase

• Verify that the 125A rating matches your circuit requirements
• Ensure the 4-pole configuration is compatible with your electrical system layout
• Check the available space in your distribution board for mounting
• Confirm that the breaking capacity meets the safety standards of your specific installation

Usage recommendations

Always perform a thorough inspection of the connections after installation and periodically check for signs of wear or thermal stress to ensure long-term reliability.
