SELECTION GUIDE
How to Select WLM8EY-400H-3300 LCD MCCB Protection and Display Functions
Specify the model, current, circuit voltage, required display functions, release settings and interface needs when requesting a WLM8EY-400H-3300 quotation from W9 Group.
Define the display requirement
Identify which operating values, settings and fault indications the panel needs. Request the display menu and user instructions for the offered release.
Coordinate electronic protection
Request the available functions, adjustment ranges and time-current curves. Confirm ground-fault or leakage requirements separately.
Check supply and fault duty
Specify the circuit voltage, prospective fault current and required 400 A, 3-pole configuration. Request the applicable Icu and Ics.
Plan monitoring and installation
Confirm auxiliary power, communications hardware and protocol only if needed. Request terminal, mounting and accessory drawings before panel manufacture.

BUYER FAQ
WLM8EY-400H-3300 LCD MCCB FAQs: Display, Communication and Ground Fault
Find answers about WLM8EY-400H-3300 selection, configuration and ordering.
Which configuration is listed for WLM8EY-400H-3300?
The product is identified as 400 A and 3 poles with an LCD. Confirm the complete release and order code with W9 Group.
What information does the LCD show?
Request the exact display menu and release manual. An LCD designation does not establish which measurements, event history or setting screens are provided.
Does an LCD mean Modbus or another communication protocol is included?
No interface is established by the display designation alone. Confirm the communication module, supported protocol, connector and auxiliary supply for the ordered version.
Which electronic trip functions are available?
Confirm the release function list, pickup and delay ranges and time-current curves. Specify the required protection functions instead of assuming a full LSIG package.
Does ground-fault protection replace sensitive earth-leakage protection?
Confirm the sensing method, pickup and trip time for the intended duty. A ground-fault function is not automatically equivalent to sensitive residual-current protection for a particular installation.
Which installation documents are needed?
Request the WLM8EY-400H-3300 wiring diagram, mounting dimensions, terminal instructions and voltage-specific Icu and Ics schedule. Confirm external sensors and accessories separately.
What is needed for a WLM8EY-400H-3300 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.
