Choose the Right Rating for Your DC System
Choose the Right Rating, Not the Largest Rating
With a 125A rated current and DC 500V rated operational voltage, this MCCB is a practical choice for DC distribution circuits operating within these electrical limits.
Clear Specifications, Easier to Compare
Choosing a DC MCCB should not be based on current rating alone. This model provides clearly defined ratings for operating voltage, insulation voltage, impulse withstand voltage and instantaneous trip setting, giving buyers the information needed to compare the breaker with their system requirements.
Why Choose 125A Instead of a Larger MCCB?
A higher current rating does not automatically provide better circuit protection. The breaker should be selected according to the designed circuit current and protection requirements.
If the circuit is designed around 125A, choosing a correctly rated 125A MCCB can provide a more appropriate match than simply selecting a larger-rated breaker.
The correct rating depends on the actual system design. A higher rating should not be selected simply because it is larger.
Make Selection and Procurement Easier
Match the Circuit, Not Just the Breaker Size
If your DC circuit is designed around a 125A current rating and operates at up to 500V DC, this MCCB provides a suitable rating for consideration. Choosing a larger breaker does not automatically provide better circuit protection.
Make Technical Selection Easier
Key electrical ratings are clearly defined, including the operating voltage, insulation voltage, impulse withstand voltage and instantaneous trip setting. This gives engineers the information they need to check the product before ordering.
A Defined Response to High-Current Faults
The 10In instantaneous trip setting gives engineers a clear reference when evaluating the breaker’s response to high-current fault conditions.
Suitable for PV and DC Distribution
The breaker can be considered for compatible solar PV and DC distribution applications where its electrical ratings meet the system requirements.
A Clear Standard for Procurement
Designed according to EN/IEC 60947-2, the product provides a recognized standard reference for technical review and purchasing decisions.
Built for Practical DC Protection Applications
Solar PV DC Distribution
For PV systems where the DC circuit operates within the 125A current rating and 500V DC operational voltage, this MCCB can be used for compatible feeder and distribution circuit protection.
DC Distribution Cabinets
A practical option for distribution cabinets that need 125A-class DC circuit protection, particularly where space, wiring and breaker selection need to be considered together.
DC Feeder Circuits
Suitable for DC feeder circuits where the designed current requires a 125A-rated breaker and the system protection requirements match the product specifications.
Electrical Control Cabinets
Can be integrated into compatible electrical cabinets to provide overcurrent and short-circuit protection for DC circuits.
