SELECTION GUIDE
Selecting an 800A Electronic MCCB with Modbus RS485
Specify the frame and ordered current, 3P or 4P, operating voltage, fault level, trip settings and Modbus requirements when requesting a WLM6EY-800 quotation from W9 Group.
Match the current and frame
The 800 A frame has a published current schedule of 500, 550, 600, 630, 660, 700, 740, 780, 800 A. Confirm the ordered rating and actual adjustment limits.
Choose poles and fault duty
Specify 3P or 4P, the operating voltage and prospective short-circuit current. Request the matching Icu / Ics table.
Define the trip settings
Request the exact trip-unit function list, setting ranges and time-current curves. Confirm ground-fault protection separately.
Plan the RS485 connection
Confirm the Modbus register map, communication settings, auxiliary-power requirements and controller compatibility before integration.

BUYER FAQ
WLM6EY-800 Electronic MCCB FAQs: Settings and Communication
Find answers about WLM6EY-800 selection, configuration and ordering.
What is the WLM6EY-800 used for?
W9 Group lists this 800 A-frame electronic molded case circuit breaker for AC circuit protection, with LCD indication and a Modbus RS485 interface.
Is every WLM6EY-800 supplied at 800 A?
No. 800 A identifies the frame described on this page; the published current schedule includes 500, 550, 600, 630, 660, 700, 740, 780, 800 A. Confirm the selected rating and trip-unit adjustment range.
Which pole and voltage options are listed?
The summary lists 3P / 4P and 400 / 690 V. Breaking capacity depends on the voltage and variant code; confirm the complete combination in the supplied datasheet.
Which electronic-trip settings are available?
The source describes adjustable electronic protection. Confirm the actual functions, setting ranges, trip curves and display arrangement for the offered trip unit.
Can the Modbus RS485 interface connect directly to my controller?
The interface is listed, but integration requires the matching register map, address and serial settings. Confirm auxiliary power and controller support with W9 Group.
Does communication provide remote closing or every protection function?
An RS485 interface alone does not establish remote closing or a complete protection-function set. Confirm the operating mechanism, accessories, trip functions and settings in the offered configuration.
What is needed for a WLM6EY-800 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.
