SELECTION GUIDE
Selecting a 250A Adjustable Thermal-Magnetic MCCB with 3P or 4P Options
Specify the required 250 A configuration, pole arrangement, supply voltage, short-circuit duty, trip-unit settings and installation requirements when requesting a WLM6RT quotation from W9 Group.
Specify the current and poles
Use WLM6RT 250 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 adjustment type, permitted setting range and commissioning instructions for the selected WLM6RT trip unit.
Check panel integration
The depth entry for WLM6RT 250 A is 68/88(h&q type) (mm). Confirm the depth and any suffix-dependent dimensions on the installation drawing.

BUYER FAQ
WLM6RT 250A MCCB FAQs: Trip Unit, Ratings and Panel Fit
Find answers about ratings, trip-unit configuration and installation documents.
What configuration does the WLM6RT 250 A page list?
The catalog lists a 250 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 WLM6RT trip unit?
See the matching model document.
How can I verify the WLM6RT 250 A panel dimensions?
See the matching model document.
What is needed for a WLM6RT 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 WLM6RT 250A MCCB?
Provide the installation voltage and prospective short-circuit current. Request the Icu and Ics data for the exact WLM6RT 250A capacity code; confirm the rating at that voltage rather than using a value from a different condition.
What adjustment range should I request for the WLM6RT 250A MCCB?
Request the adjustment schedule and time-current curve for the selected WLM6RT 250A release. Confirm which settings are adjustable and the available range for the exact order code before specifying coordination.
Which terminal and mounting details are needed for WLM6RT 250A?
Request the WLM6RT 250A mounting drawing, terminal pitch and connection arrangement for the selected pole version. Confirm conductor and busbar fit using that drawing rather than a different frame size.
