Molded case leakage circuit breaker 125A 4P

Which type of molded case leakage circuit breaker is suitable for solving ground fault problems in circuits?

The Molded case leakage circuit breaker 125A 4P can accurately identify circuit overloads and short circuits in the power distribution system, as well as grounding faults caused by insulation aging of the lines, moisture in equipment or accidental damage. This product can integrate high-breaking capacity molded case circuit breakers with highly sensitive leakage protection modules into one.

Core advantages of the product

• Comprehensive fault protection: It integrates conventional current fault protection such as overload and short circuit with professional ground leakage protection. A single device can meet the core requirements for line safety.
• Four-pole complete isolation: It adopts a true 4P design. Once it trips, it simultaneously cuts off the three phase lines and the neutral line, ensuring that the faulty circuit is completely and safely isolated without any residual potential risk.
• Adjustable leakage trip value: The leakage trip current can be flexibly set according to the application scenario (such as 100mA, 300mA, 500mA, etc.), which can be used to prevent electric shock hazards (by setting a low value) or electrical fires (by setting a higher value), adapting to different needs in industrial and commercial settings.
• Fast and reliable tripping: It uses a highly reliable electronic leakage detection module with strong anti-interference ability and fast response speed, ensuring instantaneous action in case of danger.

Application scenarios

Main distribution cabinets for commercial buildings (such as shopping malls and hotels): As the core protective devices for preventing electrical fires, they comply with the requirements of fire - protection and safety regulations.

Power distribution for new energy vehicle charging stations or pile clusters: Offer dedicated leakage protection for charging facilities to guarantee absolute safety in high - current charging environments.

Main incoming line of industrial plant workshops or regional distribution boxes: To prevent the deterioration of line insulation and equipment leakage caused by the complex environment.
