SELECTION GUIDE
How to Select a WLM8E-400H-4300 Electronic MCCB by Trip Settings and Fault Duty
Specify the full order code, selected current, poles, circuit voltage, fault duty and electronic release functions when requesting a WLM8E-400H-4300 quotation from W9 Group.
Confirm the exact configuration
Use the complete WLM8E-400H-4300 code and the required 4P arrangement. Confirm selected current and the supplied electronic release version.
Choose the required protection
Request the trip-unit function list, adjustment limits and time-current curves. Coordinate settings with the load and adjacent protective devices.
Match voltage and fault duty
Provide operating voltage and prospective fault current. Request Icu and Ics for the exact configuration instead of deriving ratings from the H suffix.
Plan the installation
Request mounting dimensions, terminal details, neutral arrangements where applicable and the accessory list. Confirm any separate control supply and interface requirements.

BUYER FAQ
WLM8E-400H-4300 Electronic MCCB FAQs: LSIG, Ground Fault and Coordination
Find answers about WLM8E-400H-4300 selection, configuration and ordering.
Which configuration does the WLM8E-400H-4300 page identify?
The native title identifies 4P and 400 A for WLM8E-400H-4300. Confirm the complete order code, selected current and trip-unit version before ordering.
How are electronic trip settings selected?
Request the exact release code, function list, setting ranges and time-current curves. Choose settings from the load and coordination study rather than inferring them from the breaker model digits.
Does the H suffix establish the breaking capacity?
The suffix is part of the model code. Confirm the numerical Icu and Ics at the actual operating voltage and pole configuration using the corresponding rating schedule.
What does the LSIG designation cover?
The native title uses LSIG. Request the supplied trip-unit definition and its long-time, short-time, instantaneous and ground-fault settings. Confirm the ground-fault sensing arrangement; do not assume personnel earth-leakage protection.
Can the breaker open and close remotely by itself?
An electronic trip unit does not establish a remote-closing mechanism. Confirm any shunt release, motor operator, control supply, interlocks and feedback contacts required for remote operation.
Which documents are needed before switchboard integration?
Request the WLM8E-400H-4300 datasheet, pole and terminal diagram, time-current curves, mounting dimensions and accessory compatibility list. Include the required supply and fault-duty conditions in the enquiry.
What is needed for a WLM8E-400H-4300 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.
