선정 가이드
How to Select WLM8-400H-4300 Thermal Magnetic MCCB Trip Curves and Fault Duty
Specify the model, required current, poles, circuit voltage, load starting duty and prospective fault current when requesting a WLM8-400H-4300 quotation from W9 Group.
Match the load and release
Specify the load current, starting behavior and coordination needs. Request the thermal pickup and magnetic trip characteristic for the selected version.
Select the pole arrangement
This model is listed as 4P. Confirm terminal identification and any neutral-pole treatment using the actual connection diagram.
Verify voltage-specific capacity
Provide the operating voltage and prospective short-circuit current. Request the applicable Icu and Ics rather than selecting on current or a suffix alone.
Plan the panel connection
Request mounting dimensions, terminal sizes, connection hardware and tightening instructions. Confirm accessory compatibility by the complete breaker model.

WLM8-400H-4300 Thermal Magnetic MCCB FAQs: Overload and Short-Circuit Selection
Find answers about WLM8-400H-4300 selection, configuration and ordering.
What configuration is listed for WLM8-400H-4300?
This product is identified as 400 A and 4P with a thermal-magnetic release. Confirm the complete offered configuration before ordering.
What is the difference between the thermal and magnetic functions?
The thermal function addresses sustained overloads and the magnetic function addresses high fault currents. Request the exact time-current curve to determine pickup and operating time for the offered release.
Can the trip current be adjusted?
Confirm whether the supplied release has fixed or adjustable settings and request its adjustment schedule. A thermal-magnetic designation does not by itself establish a selectable current range.
어떤 단락 차단 용량이 적용됩니까?
Confirm Icu and Ics at the actual circuit voltage for this complete model. The H suffix and current designation are not substitutes for the voltage-specific rating schedule.
Does it include residual-current or earth-leakage protection?
Confirm a dedicated leakage release or a coordinated separate device if residual-current protection is required. A thermal-magnetic release description does not establish leakage sensitivity or a residual-current trip function.
Which accessories and installation documents should I request?
Request the WLM8-400H-4300 mounting and terminal drawing, wiring instructions, time-current curves and accessory compatibility list. Confirm auxiliary contacts and powered operating accessories separately.
