SELECTION GUIDE
Selecting a 125A Thermal-Magnetic MCCB with 3P or 4P Options
Specify the required 125 A configuration, pole arrangement, supply voltage, short-circuit duty, trip-unit settings and installation requirements when requesting a WLM6 quotation from W9 Group.
Specify the current and poles
Use WLM6 125 A in the enquiry and state the required 3P or 4P arrangement. Confirm the rated current and full order code on the quotation.
Check fault duty at the supply voltage
State the supply voltage and prospective short-circuit current. Request the selected capacity code and its ultimate and service breaking ratings.
Match the trip unit
Request the thermal-magnetic time-current curve and confirm that it matches the load and upstream protection.
Check panel integration
Request a dimension drawing for the selected pole and trip-unit configuration.

BUYER FAQ
WLM6 125A MCCB FAQs: Trip Unit, Ratings and Panel Fit
Find answers about ratings, trip-unit configuration and installation documents.
What configuration does the WLM6 125 A page list?
The catalog lists a 125 A current designation, 3P or 4P options and working voltages of 400 V and 690 V. Confirm the exact configuration and its marked ratings before ordering.
How should I specify the WLM6 trip unit?
Request the matching trip curve and coordination data for the selected device.
How can I verify the WLM6 125 A panel dimensions?
The depth entry for WLM6 125 A is 68 (mm). Confirm the depth and any suffix-dependent dimensions on the installation drawing.
What is needed for a WLM6 quotation?
Send the required configuration, quantity, destination market and document requirements. Price, minimum order quantity, sample availability and lead time are not published for this product; confirm them with W9 Group.
How do I choose the breaking capacity for the WLM6 125A MCCB?
Provide the installation voltage and prospective short-circuit current. Request the Icu and Ics data for the exact WLM6 125A capacity code; confirm the rating at that voltage rather than using a value from a different condition.
Can the WLM6 125A thermal-magnetic MCCB be selected for a motor circuit?
Provide the motor load and starting characteristics and request the approved WLM6 125A trip curve for that duty. Confirm the offered protection configuration; the frame-current designation alone does not establish motor-circuit suitability.
Which terminal and mounting details should I confirm for WLM6 125A?
Request the WLM6 125A mounting and connection drawing for the chosen poles and installation arrangement. Confirm terminal spacing, conductor access and busbar fit before preparing the panel.
