SELECTION GUIDE
Selecting a 160A Adjustable Thermal-Magnetic MCCB Trip Unit
Specify the selected current, release suffix, adjustment functions, poles, operating voltage, fault duty and panel arrangement when requesting a WLM6RT-160 quotation from W9 Group.
Identify the current and suffix
The adjustable catalog row lists 25–160 A choices. Confirm the ordered rating and whether overload, instantaneous or both settings are adjustable.
Match the time-current curve
Request the selected trip curve and permitted setting ranges. Confirm coordination with the load and upstream / downstream protection.
Check voltage and fault capacity
Specify the operating voltage and prospective short-circuit current. Confirm Icu / Ics for the actual pole and capacity-code combination.
Verify panel integration
Request dimensions, terminal arrangement, mounting and clearances for the selected version. Confirm every suffix-dependent dimension before assembly.

BUYER FAQ
WLM6RT-160 Adjustable MCCB FAQs: Settings, Poles and Fault Duty
Find answers about WLM6RT-160 selection, configuration and ordering.
Is the WLM6RT-160 page for a 125 A or 160 A breaker?
The native summary and frame table identify 160 A. The old title also contains 125 A. Confirm the ordered current and full suffix rather than relying on that mixed title.
Which adjustable-variant currents are listed?
The adjustable rows list 25, 32, 40, 50, 63, 80, 100, 125, 140 and 160 A. These are catalog choices; confirm the adjustment limits of the actual release.
Are overload and instantaneous settings adjustable on every version?
Do not assume both. The source separates adjustable variants by suffix. Confirm the selected release functions, pickup ranges and time-current curve.
Can one fault rating be used at both voltage options?
No universal rating is assigned. Confirm voltage-specific Icu / Ics for the capacity code and pole arrangement; the copied matrix has ambiguous row headings.
How should I choose 3P or 4P?
The summary lists both. Provide the circuit and neutral requirements, then confirm the switching arrangement and installation drawing for the chosen device.
Can I use the catalog dimensions for the final switchboard?
Use them only after matching the pole arrangement and suffix. Confirm mounting, terminals, clearances and any depth variants in the approved installation drawing.
What is needed for a WLM6RT-160 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.
