SELECTION GUIDE
JCB3-125DC high current DC MCB selection
Specify the complete order code, circuit duty, installation conditions and required documents when requesting a JCB3-125DC quotation from W9 Group.
Define the supply circuit
Provide the supply type, maximum circuit voltage and earthing arrangement. Confirm the required pole connection from the matching wiring diagram.
Coordinate current and release
Choose the ordered current using conductor and load duty. Request the exact trip curve and any installation-related derating.
Compare fault interruption
Provide the prospective short-circuit current. Confirm the breaking rating, operating voltage and applicable test standard together.
Check installation details
Request terminal limits, mounting dimensions, torque and accessory compatibility for the complete model code.

BUYER FAQ
JCB3-125DC DC MCB selection FAQs
Find answers about JCB3-125DC selection, configuration and ordering.
Does the maximum DC voltage apply to one pole?
No. The summary states up to 250V DC per pole and identifies the four-pole version for up to 1000V DC. Confirm the exact diagram and voltage for the ordered pole arrangement.
Which currents can I order?
The summary lists currents up to 125A. Request the complete current-option schedule and matching trip curve; the maximum is not a statement that every unit has the same current.
Is the breaker non-polarity?
A non-polarity connection is not established by the available target summary. Confirm terminal polarity and permitted current direction from the exact wiring diagram.
How should I verify the breaking rating?
The supplier lists 10kA. Confirm its DC operating voltage, pole connection and test conditions before comparing it with the prospective fault current.
Can an AC-rated breaker be substituted?
Confirm a dedicated DC rating and connection arrangement. AC ratings alone do not establish suitability for interrupting a direct-current fault.
What installation details should be requested?
Request dimensions, terminal conductor limits, tightening torque, enclosure requirements and any DC-specific connection instructions for the selected version.
What is needed for a JCB3-125DC 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.
