SELECTION GUIDE
How to Select CSDM7-125L-4300 Thermal Magnetic MCCB Trip Curves and Fault Duty
Specify the complete model, rated current, poles, operating voltage, load duty and prospective fault current when requesting a CSDM7-125L-4300 quotation from W9 Group.
Coordinate overload and starting current
Compare the 125 A designation and release curve with load current, starting behavior and conductor protection. Confirm the selected release settings and installation conditions.
Check the neutral-pole arrangement
The CSDM7-125L-4300 designation is 4P. Confirm neutral switching, neutral protection and the connection sequence from the exact wiring diagram; four poles alone do not define all neutral functions.
Verify fault duty by voltage
Request Icu and Ics at the actual supply voltage. Compare them with prospective short-circuit current and the project coordination requirements, not a suffix or application label alone.
Confirm the physical connection
Request mounting dimensions, terminal conductor limits, cable or busbar details and tightening instructions. Confirm each accessory by the complete host model before panel manufacture.

BUYER FAQ
CSDM7-125L-4300 Thermal Magnetic MCCB FAQs: Neutral Switching and Fault Ratings
Find answers about CSDM7-125L-4300 selection, configuration and ordering.
Which current and pole arrangement does CSDM7-125L-4300 identify?
W9 Group lists 125 A and 4P for CSDM7-125L-4300. Confirm the complete order code, selected release and installation conditions before ordering.
Which working voltage is listed?
The product summary lists 380V/415V. Request the matching operating-voltage and fault-capacity schedule. These designations do not establish a DC rating or every intermediate-voltage configuration.
Which short-circuit breaking capacity applies?
The supplier product description states 25 kA. Confirm whether this is Icu, Ics or another declared capacity and obtain its operating voltage and test configuration before selecting the breaker.
How do thermal overload and magnetic short-circuit protection differ?
Thermal protection responds to sustained overloads; magnetic protection responds to high fault currents. Use the exact time-current curve to coordinate protection with the conductor, load and upstream device.
Does the four-pole version protect the neutral against overload?
Confirm neutral-pole protection and switching behavior from the exact release and wiring documents. Four switched poles do not by themselves prove neutral overload protection or a particular switching sequence.
Are the thermal and magnetic trip settings adjustable?
Request the release legend and time-current curve. Confirm whether each setting is fixed or adjustable and the permitted range; the rated current alone is not an adjustment schedule.
What is needed for a CSDM7-125L-4300 quotation?
Send the required configuration, quantity, destination market and document requirements. Ask W9 Group to confirm price, minimum order quantity, samples and lead time for the selected configuration.
