SELECTION GUIDE
How to Select a 1250A MCCB with Adjustable Overload or Instantaneous Trip
Specify the ordered current, release suffix, adjustment functions, poles, operating voltage and fault duty when requesting a WLM6RT-1250 quotation from W9 Group.
Select the current and release
Use WLM6RT-1250 with the required catalog current. Confirm whether the selected release adjusts overload, instantaneous protection or both.
Coordinate the protection curve
Request the time-current curve and allowed settings for the actual release. Match the settings to the load and adjacent protective devices.
Match voltage and fault duty
Provide circuit voltage and prospective short-circuit current. Confirm the capacity code and corresponding Icu / Ics.
Check the installation drawing
Confirm pole count, terminal direction, mounting form, clearances and dimensions before preparing the switchboard.

BUYER FAQ
WLM6RT-1250 Adjustable MCCB FAQs: Trip Settings, Poles and Fault Ratings
Find answers about WLM6RT-1250 selection, configuration and ordering.
Which current choices are listed for WLM6RT-1250?
The target catalog lists 630, 700, 800, 1000, 1250 A. These are available catalog choices, not a promise that every release adjusts continuously across the full range. Confirm the ordered current and suffix.
Does every version adjust both overload and instantaneous protection?
The catalog separates adjustable variants by suffix. Confirm each required adjustment function, setting range and time-current curve for the supplied release.
Can the same breaking capacity be used at both operating voltages?
Confirm Icu / Ics for the actual voltage, pole arrangement and capacity code. The source matrix has ambiguous headings, so no single fault rating is assigned to every version.
How do I select the pole arrangement?
The summary offers 3P / 4P. Specify neutral switching requirements and request the drawing matching the selected arrangement.
Is this an electronic controller or a thermal-magnetic release?
This page covers the adjustable thermal-magnetic model designation. Confirm its release suffix; electronic-controller functions from other product families are not included by assumption.
Which mounting and connection details need confirmation?
Request the approved drawing for fixed, plug-in or withdrawable construction as applicable. Confirm front or rear connection, terminal clearances and the ordered accessory combination.
What is needed for a WLM6RT-1250 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.
