2 Pole 125A AC Molded Case Circuit Breaker

In single-phase 220V or specific two-phase AC 400V distribution networks, when the load power climbs to tens of kilowatts, it poses a serious challenge to the current carrying capacity, breaking performance, and reliability of line protection equipment. The SPX customized 2 Pole 125A AC Molded Case Circuit Breaker is a professional solution to address this challenge. It is like an experienced "circuit commander", not only carrying the arduous task of continuously delivering 125A current, but also constantly alert to any abnormal overload and short circuit risks on the line, ensuring the smooth and safe operation of the main power road.

Advantage

The internal arc extinguishing system is optimized for breaking the arc generated by AC current, using multi grid segmentation and cooling technology to ensure that the arc can be quickly and safely extinguished in the event of a short circuit fault, limiting the fault energy.
The protection characteristics of the CE-certified 2 Pole 125A AC Molded Case Circuit Breaker bimetallic strip (thermal trip) and electromagnetic coil (magnetic trip) are calibrated based on the effective value of AC current to ensure the accuracy, timeliness, and stability of protection under AC sine wave current.
The overall die-casting shell is made of high-strength, arc resistant, and flame-retardant insulation materials. The internal current carrying components and contact system have high mechanical strength and can withstand the electric force and thermal stress generated by high currents. It is suitable for use in general industrial environments where vibration or environmental stress may exist.
The operating handle has clear "I" (closed) and "O" (open) markings. After the fault is tripped, the handle will move to the middle position, providing a visual indication of the fault.
When the handle is placed in the "O" position, it provides a visible air gap isolation point that meets safety standards, providing crucial electrical safety isolation for backend equipment maintenance and repair personnel.

Application

The SPX high quality 2 Pole 125A AC Molded Case Circuit Breaker serves as a single-phase main incoming switch for independent shops, restaurants, data center modules, and telecommunications base stations in small and medium-sized shopping malls.
